I really like it but..............
the perspective isn't GKish
most squares, even large ones, don't recede in the back, at least not to the angle this slops, towards the back, it looks like it's designed for a view where you can see a horizon above it in view.
In general, if a building is 20 x 20 it will use 20 by 20 tiles, etc.
A good example is the bogenera houses, or the castle walls, which don't slope backwards at all.
You have the 'up slope' nailed perfect, where you have the doors and the vertical elements wider at the top than the bottom.
It's a great graphic, but I do think the receeding angle needs to be adjusted.
Good work!
