Thanks, Gorman, I'll give scanlines a try now.

EDIT: Nevermind, I lost the .psd :P

Very Mapleleafy.
The massive blotch of grey is kinda boring, add some highlights or something on top of it, the blue parts around it just doesn't but it for for. Even for the style you were actually going after, some of the edges should be round if they're forming an arc or round edge, looks really unprofessional and simple. Some proportions are out that give it an odd feeling that's very unsatisfactory imo.
The idea's good but as I said, it's really looks like something that Mapleleaf would've made, but possibly better shaped and less bland in some areas.
I don't particularily like it, but the concept, I suppose, is nice.
