I liked the concept but I was a little bit disappointed by the last photo. When I think of a wall mural, I think of something BIG! Had I been doing it I would probably tried to cover more of the wall space.
Maybe I'm just grumpy engineer, but I feel like the design got progressively worse. The initial "ENIAC" sketch would have been pretty nice as is, but I can't say that I like the final result. Sometimes just less is more.
