Very sharp!  I think I need to do some decorative paint on mine...I just slapped on white because I had planty and needed to get the wood sealed, but man is it stark looking!
The only problem I see is there is a lack of ventilation.  From what I've seen in researching, even cold climates need a large vent area to prevent chicken lung damage from the ammonia in waste. 1 square foot per chicken, is what I read, even though that sounds like quite a lot to me!
If you cover the vent with hardware cloth, you can always use a sheet magnet to block it or partially block it (they are inexpensive, and you can even paint a design on them!)  You could also incorporate a ridge vent with that design.
Good luck, and keep posting with your progress!
