It's a good body and some real nifty colours, but I think it could do with some cleaning and sharpening work; You have dark outlines on the purple and some of the blue - but not on the yellow. I think they should be abit darker, to fit relatively. You should probably also take more care to your middle shades, use them more to follow the edges between the shades, in order to blend with them. Why do you sometimes use dither? Just curious, I'm not sure it's good on this tiny character - but I'm not good at dithering, I prefer making blend shades, so... The style of the armgear doesn't really match the rest - especially 'cause of the dithering, but also its desaturation towards the brightness of the rest, and its shape.

Hope that's the right critique you wanted
