I think the back of the house could use a little dimension...it all seems a little flat right now and not sure how that will look from the exterior? I don’t know if there’s any specific nice view out the back that you want to preserve/enhance, but having 1-2 bump outs might be nice. They could also get you some new windows in different directions, bringing in some different light. For example, you could bump out your living room so it’s not in a flat plane with the rest of the house. If your living room currently has a western exposure (I forget what the orientation is), you could then get north and south exposure by adding windows along the sides of the bump out. You could maybe even add some doors to the outside on the side of the bump out so you don’t have to squeeze by the dining table to access the sliding door - that’s how my house is currently and it is sort of annoying sometimes. I’m not an architect, so I don’t know the term for it, but adding a little dimension along the back might be good, unless you’re going for a super formal symmetrical aesthetic, which I don’t think you are.

Just a random (maybe obvious) point, a mountain house favors taller ceilings than a lake house. I am super energy conscious but I don't necessarily agree with the arguments about taller ceilings and energy use. Of course it uses more energy but that is also easy to compensate for. Large windows are a lot harder/more expensive of an energy hit - depending on orientation. It is possible to get wall based heat losses to near zero. Windows are always a lot worse. So having 8 foot tall wall of glass is worse than normal windows on a 12 ft ceiling for example. Presumably this build is in Canada which generally has very strict codes - and plenty of hydro already built....

if you want it to look really nice, just get some canned lights. It will offer far more lighting and look 100X better. Then you could do a single, larger sized pendant (say, 14-16") centered over the island. right now it looks like you removed a dining table, put in a small island, but left the dining light hanging where the table used to be. Either center it, or remove it and do all cans. see? recessed lighting, and two mini pendants. or do one larger one

A little more explanation leading up to a lighting suggestion after reviewing your provided layout: In general concept, when you place recessed-style ceiling lighting at the counter edge, you are providing task lighting on your counter workspace as well as simultaneous throw onto the floor adjacent to the cabinet. So the fixture is providing general ambient lighting for the room, but since the kitchen functions require more footcandles, these ceiling lights provide the high lumens needed for task lighting and you exploit those. Your upper and lower cabinet interiors/drawers will also be well-lit, without the shadow caused by the person standing there. With most lumenaires, because of it's ~12" placement away from the upper cabinet you will get a small hotspot or visual cone on the door, but that is a tradeoff to solving the task lighting with a catch-all solution. Because undercabinet lighting is close to the surface (both counter and backsplash) and it's cone of throw is "fenced in," a fixture style with lower lumens is chosen rendering it more of a "supplemental" lighting to the task lighting of the ceiling fixtures. But, you cannot strictly define it as only task lighting because of the low lumens, the sometimes haphazardness of upper cabinets to your work surface, and it's exploitation for accent lighting and layering in concept. You could raise the lumens to focus on task lighting and limit ceiling fixtures to ambient, however you are sometimes left with a poor solution where you can't balance the lighting between ambient, task, and accent, nor provide task lighting where you need it, illustrated in this example: Of course, these principles are general solutions to what you will be presented with in most kitchens. That is, using fixtures that are efficient in cost, installation, and aesthetics, thus a lumenaire that can cover a combination of ambient, task, and accent lighting to some degree. If your project's characteristics have attributes that need a little adjustment in the strict definition of which fixtures provide which lighting methods, then that is completely acceptable. You would see this often with high-end kitchens, specific design aesthetics, prominent circulation, some galley kitchens, or non-mainstream cabinet layouts. _____________________ Looking at your specific perspective drawing, you have an entirety of 24" deep upper cabinets and very minimal wall counter space. So if your kitchen genre calls for an efficient solution to lighting, then I would suggest 3" recessed cans which can be spaced closer to each other and have no choice but to be placed within the aisles. However, the primary purpose of these is to provide task light within the upper and lower cabinets, so they would not be centered over walkways in a grid to light up your path, but placed appropriately for a cabinet/set of cabinets. Then with the 3 enclosed wall counter spaces, where the range (which the hood will probably have it's own spots) and beverage appear to have the uppers too high to have accent lighting double as supplemental counter task lighting, utilizing under cabinet 2" ("puck style" if need be) fixtures directed at the counter. As far as the island and pendants, it may be too tight of a width of room, too much vertical orientation with the tall cabinets and mostly skinny-width doors, in what looks like a 9' ceiling, and no location where you would get a broad, setback, visual perspective to appreciate the proportion of any pendants, all of which might render the pendants "invisible" but at the same time cluttering the visual of the cabinet faces. And along with your non-symmetrical sink placement and only 3.5' counter width, it may be best to only have recessed lights. But, it just depends on the pendant fixture chosen, how transparent and how well it can provide task lighting, and your cabinet finishes/styles. Along the beverage wall I would definitely place uplighting to the ceiling and make sure the lumens balance with the counter lighting below. If your aesthetic and budget is at a higher level, say to match the rest of house or tigerwood cabinets, then another route is for 2" ceiling fixtures (which would have more design-oriented lumenaire selections) and they would light the walkways with general ambient light, but the interior of cabinets would need a light for each shelf.
