Now that, is one heck of a scratch sprite sammy! =3 I love it, and it doesn't seem to need any improvements other than, maybe, some more detail? I'm thinking...sort of, victorian designs, maybe? It's up to you though.
Moving on to my sprite...
Well, obviously, this isn't the best sprite I've ever done, for sure, but it was a nice practice sprite to make, and it might've turned out better if I didn't choose the pokemon I used randomly.
Enjoy, I hope.
