thanks 4 the tip ive re shaded them but unfortunetly their not game insertable
Spider: Hmm... See, Pokemon sprites face bottom left, rather than straight at the player. So try to make its face look bottom left. As I said before, that spider only contains not even eight colours. And can you see that one leg is behind the other? Well make the legs in the back darker.
Hand Thingy: What is that? Get rid of the default colours.
Fish: Probably your best one, you should probably change the contrast of the colours.
Snake: Oh come on, no one saw through that edit? But for a first edit, that's pretty good.
