I would say that the transom could be the same material with the same pattern, it could be the same shape with a single lite (which would be transitional really but that's ok) or it could be rectangular with upright rectangular divided lites. The mirror idea, to me anyway, is only effective if you are doing it where you actually Couldn't or Wouldn't Want to have real windows. I think the important thing to maintain with the number of openings that are adjacent here (5?), and the number of doors to be used here (5-6?) is some sort of consistency or logic behind the choices. I think if you don't have a leaded surround right at the front, you probably should not do it on the inner doors because it adds another material. Likewise the solid doors should have some kind of pattern relationship with the other solid doors, and the doors with glazing should have some kind of pattern relationship with the other glazed doors...and ideally they should have a relationship with each other as well.

Several back doorsways. They are doorways that are in relatively large walls.This may be too difficult to explain....but I will try. House is a ranch with walk out basement. On the main level: One doorway is a 8 foot tall set of double French doors flanked by two foot windows toward the end of a 40 foot long x 12 ft wide screened porch. Entrance is straight on from porch. The porch will have three fans with led lights so we are thinking no light per se for this doorway as neither wall sconces nor an overhead would work. Another French door is from a sunroom onto a 6x6 landing. This landing entrance is straight on and also connects to the screened porch. To the side of this door is the 20 foot wall of sunroom windows. We are thinking a 21" tall x7.5 w fixture here on the sunroom window side. The sunroom walls are in Hardie plank, so it has an exterior look. Inside the sunroom are two entrances both of which are French doors. One is straight on entrance and the other is a 90 degrees turn on the wall abutting (doors are basically together in a back corner). Each of these single French doors is 3/0x6/8. We are thinking same fixture as 8/0 door but in 16" height x 6"w one for each door. Finally on lower level, under the porch is a 3/0x6/8 French door. It is almost in the center of the 77 foot length of the house. We are thinking same fixtures as above in the 16" height. The lower level ceiling will be finished out with three overhead light fixtures..flush type same line as the doorway fixtures. We were also going to use the same 16" high fixture on the garage stoop door. Straight on, 18" overhand at the end of a 24 foot wall. We are a bit concerned the fixtures are too big.

I'm actually with your friend! love the dark w/your stone AND some type of cedar or redwood. i'm confused by your pictures. why do they look like two diff homes? If that's your landscaping, may I suggest quite a bit of pruning and cleaning up before doing the home? I can't even tell what I'm looking at! these are all dark w/cedar accents

Not really anything that you can with trim around the door because the top of the door is so close to the soffit. I built a small cedar planter box out of some scrap cedar that I had and hung it beside my front door. 16" long x 7" wide x 6" deep. During the summer, I plant it with impatiens. In the winter, I arrange cut evergreen boughs in it. Something like that or a decorative mail box would look good on your house, soften things up and add some color/ interest.
