My Pokemon Revamps

[mango]

mine isnt perfect but id thought it help give you some tips.

1. dont be afraid to change the outlines of the original sprite.

2. use black outlines for the darker areas of the body. you did some of this on the ears but not on the body.

3. try to not use all of the same highlights/shades the original sprite has.

4. use shades and highlights to contour some parts and make them stick out more. (sorry, i dont know how to explain this well)
ex. on your pikachu's left leg (our right), the shade on the leg makes it seem weirdly flat. and it doesnt compliment the outlines of the leg.

5. not every part needs a highlight or shade (or at least a lot of it). if you're not sure try and look at the reference to figure it out.
(mainly about the arms)

i hope that helped.
