Nice looking coop. A few thoughts:
Having those half posts scabbed onto the fence posts doesn't look too good; I think you'd be better off running them to the ground. And the one on the end, hanging in mid-air, is a problem. I'm assuming it is attached to the fence rail - I have a picket fence like that, and those rails do not offer much lateral support - adding that roof load to it will cause it to bow and probably pull out of the fence posts.
You might find it convenient to locate the chicken door between the coop and the pen close to the edge, so you can close it at night from the outside.
So, what will it be, Rhode Island Reds, New Hampshire Reds, White Leghorns, Plymouth Rocks, or some exotic breed?
