Inspired by the thief universe and the awesome concept art out there :). Super tricky to get it to look right, need a lot more practice. Thought up some generic story about a fat judge living inside the tower and once mission is to take him out and avoid being seen. I started to play around in sketchup and modeled the houses and such then painted/textured in photoshop. Playing around with the process, fun stuff :)
Aaand some 30 min sketches.
Take care ppl!
