The Pixels Of Joxon

[Sketchasaurus]

The colors are much too dark in general and they bleed together too much. I'd suggest having a look at the colors used in CaveStory if that's the type of style you're aiming for. Dark Clothing simply doesn't work well for character sprites at such small sizes. it's very hard to read the sprite at its normal size against a white background because all of the colors are bleeding together against the background.
