A little bit of architectural advice, fix the lack of overhang on the sides of the roof, that immediate change from the gray of the moulding to the black of the roof is a bit unsightly, so I'd suggest you use the double-sided ramp bricks to put a definite layer difference between the roof and the wall.
[edit]
But still very excellent.
Your work = 10/10, the build = 9/10 until aesthetic issues are corrected.
