Shingeki no Kyojin: the chaos within the walls

This is a "Shingeki no Kyojin" (also know as "Attack on Titan") fanart which doesn't feature any of the famous characters. Instead I wanted to focus on the concept of the beautiful undiscovered world outside the walls and the chaos within themselves. I find it very poetic that the real danger is on the inside.

I wanted to make a few supply boxes for the ammo of the cannons but I'm very tired and I won't continue any further.
