I don't think you need the darkest brown colour, since it's so dark: *Care*
I also think you could replace your second-to-darkest orange colour with the darkest one: Kinda uppdated.
You should also get rid of the dark line (or even both) on the top edge of the holes in the pumpkin: ?
Oh yeah also why does it have a black background: Because i like black backgrounds. :D
