Good work, nice blending with the desert tiles, did you use some other map as template? Can be quite tricky to make it look good if you do it from scratch.
I like the broken Mr Handy at the scrapheap also, nice touch.
The city tile edges towards the desert in the workshop looks a bit weird together with the tin walls, but there's not much to do I guess if you want to have an open space without garage doors, since a straight tile would look worse, and the stone tiles makes sense in a workshop.
