Sure, I would most likely do something like this..
Looks good, though I may take it in a different direction when it's all said and done as far as colorscheme goes. That's good!
I think the art style is a little too different though. If you look at the Bender-like robot on the upper right, you would expect a game full of bendy robots, possibly chrome-plated. The cartoon-character looking one simply doesn't jive (unless you are going for a Toy-Story feel where every robot is radically different).
That is what I am going for. In this game, the setting is a little village that a jolly old scientists made for his robots. You are his latest creation and you enjoy your time in the village. The point of the game, directly, is to have fun. In others, it may be destroy Badass XYZ or collect these SUPAH-THINGS. But this one will just say 'Have a good time.'
