These are a couple of prison concepts I've worked on. I like the idea of having a very simple fortress kind of structure. It looks quite menacing especially with the smaller cell windows and this could look really nice as our final shot before the credits. Also the concepts give a good impression of how the colouring can change the mood. We have a lot of artistic license with the shades in the sky and we will definitely use this to full advantage in final renders etc to get the mood and tone of the film right.
