Industrial lighting is so in vogue that you can find industrial style lights in nearly any store or company that sells lights. Lowe's and Home Depot even now have industrial-style pendant lights. In addition to Barn Light Electric, School House Electric (my fave in the bunch) and Rejuvenation Hardware sell a variety of industrial-style lights (not to mention FH and PB). For a great selection of antique and restored industrial lights, PW Vintage lighting in Great Barrington MA is a great resources. They have a useful website.

This is a nice room, but it does need some personality and color. I would definitely involve your son and incorporate his interests. Here are some ideas from Target to get you started. I'm sure PB Kids and others will have similar looks. A bulletin board over the desk is a great idea, along with colorful art. Sports, Star Wars, oceans... you can always preselect several pieces you can live with that he will like and let him make the final choice. The mirror can go over the dresser if it will be useful, otherwise stick with decor that appeals to him. It is hard to tell from your photos if there might be a better furniture arrangement since that big bed doesn't leave much space for playing or storage for books and toys.

I love your countertop slabs, they are stunning. Based on all the criticism I looked at your layout and I see a lot of positives. You have a sink for cleanup near the dishwasher drawers and stove, and a second sink for prep work. That sink is not far from the fridge, so you can grab an armload of produce and get right to work ... and as you work the kids who just want a drink or snack from the fridge can get it without coming into the work L. This isn't a studio apartment, it is meant to work for a large family and so yeah, you may need to take 2-3 more steps to get around but that is somewhat unavoidable. For lights ... maybe something like this if you want something bold that isn't adding a lot of color: Huddardton Forge Erlenmeyer Flask Pendant Just a thought. Congrats on the new house. Don't worry about the people here who enjoy shooting arrows of doubt and dismay without offering to help identify ways to improve things. Some people naturally look for flaws and love to point them out (instead of asking why something was designed this way vs that way). It can't be a fun way to live life.

Are we talking about the "entry" right at the front door? Or the space up on the step up area toward the stairs. Basically, though, it's the base of the table that will somewhat define the style. The more rustic, it becomes more "Mountain lodge" and the more refined it can go modern, contemporary or even more "transitional". They are also pretty expensive so before you invest money there, figure out how much you want to or can spend now, and then start selecting things you like and create an "Ideabook" here on Houzz. That will help you "define" which style direction you like. You can "like" a number of styles, but ultimately one will become more apparent than others.
