A Beginner's Journey

[Omega]

First off welcome to the wonderful world of Spriting *throws confetti everywhere*

First off lets start with something simple and talk about the shading.
Right now your character has two different sources of light, one on the left and one in front of him.

When doing top down perspective sprites the light source should usually come from the top, so the hair piece (?) should have darker colors on its side.

Places the light cant reach, like the neck should also have a dark color around the area too.

hope this helps.
