It's cute, first of all. But is it me, or is there something uncanny about Bomberman here? I've been sitting here trying to figure out what's wrong, but they seem more 'empty' than usual. I don't think the Bomberman in the top right with it's screen broken helps.
Edit: Went through some other Bomberman art, and I think the problem here is the eyes.The eyes are smaller than normal, and there are no eyebrows by default. Those two points make the face seem 'lifeless' when Bomberman isn't doing anything. It's not a problem in the other doodles, where Bomberman is doing stuff, but still.
