Zone Mortalis Tiles Project - Painting Progress

I have been slowly working on painting all 18 of those monstrous but really cool tiles. This is a little update so you can get the idea of what I am going for with the colors and style.

4 year old for scale.

I still have a ways to go, some washes and more colors. Also I need to paint up the door pieces, of which I am thinking of a military green. When I played a few games in these with my brother, and everything was grey painted, we found it difficult to pick out the doors in it all. So only the doors had to be a different color than the rest of the floors or walls.
