Custom Pokémon

[missingno.]

shading is flat and ignores form of the character,
character is a poor choice for learning as even if you perfect this you will still need to learn more for characters with anatomy,
colour choice is poor, lack of contrast and colour curve doesn't help that flat feel.

my advice, try and make a mewtwo.
It may be a massive jump but in doing so you will be able to learn;
shading of complex forms, use of multiple colour curves (one for the pink other for the purple), anatomy, posing, and in the faces case, pixel limitations and how to overcome them.
come to think of it any humanoid pokemon should work (I only say pokemon to keep it relevant to the topics title)

in any case, welcome to the community, look at the stickied topics, the spriters dictionary in particular may be for use to you.
looking forwards to seeing you progress.

ok will do
