The flattened perspective looks a bit odd to me, particularly on the roof. But the texture work is amazing!
The texturing here is brilliant. You could clean it a bit for PJ classic pixel art standards. It is obvious that such detailed piece will have a lot of colours, but you really don't need to have few bricks with separate individual colours reserved just for each one of them. Check details here, especially for colours used for less thatn 0,1%.
this is so damn good, i just keep staring at it :o
