I think this is shaping up to be my best box so far. I went for a comic book look for the front. If you think the blank colour panes are too strong or wont work, look at the 2 completed ones and imagine that in all the spaces. I think it will look great. And yes I will try my best at a back, I have some great ideas.
Remember this is a WIP so I havent added the Dev. logos and stuff yet.
