I love this. My only suggestion would be switching up the background color to provide more contrast between the GC and the background. Other than that, this is really cool. You should do the entire Nintendo console lineup!
Hrm, maybe try fixing up the composition of it maybe?? Like maybe move the gamecube itself in like a rule of 3rds location. That might make the piece a bit more interesting. Maybe make the Gamecube a bit more square. Hope my tips help.
I went directly off of the real GameCube for the shape. I could make it square, but it would really mess up the proportions. I'll put it in the bottom right 1/3rd when I get a chance. I was also thinking about making a controller to sit beside it?
