Thanks for the Criticism,

Yes, I have some problems with the construction of a pallete/hue shifting, the shading and the perspective, i'm go to training this bad point to be bether. You have any tip?

Sorry by the bad english :/

I like this concept =)

Nice colors, but the palette isn't very well built. Some colors are very close and hard to tell apart; you also need better hue shifting (organise the colors by hue (H) and you'll notice there are only 5 different, one being used in 5 colors; same thing for saturation S).
You'll find it also helps for better shading!
