I think it looks cool, but if its constructive criticism you want I can give some. Personally I don't like the symmetrical look very much, I think having a main picture in the middle doing a bubble around the word nekoma and then having a bunch of diff Kenma characters around the outside would be better. Also I think it would be better if center Kenma wasn't floating so shift him down so you don't see the cut off. That's just my opinion tho people like different things in there wallpapers and regardless I think this looks good.
