Any feedback is really appreciated; character design, colors, technique, lighting, stylization.  Anything, really. 
It's for an RPG I'm working on.

It was commissioned and then edited (I forgot who I commissioned for it - I'm sorry)

I dont know how much colorful is your game but I have a rule when creating characters, to never use more than 3 main colors on my characters, and of course you need to follow some color combination based on color theories. For characters I recommend to use only one of these combinations: complementary, analogous, split-complementary, or triad. I made a quick edit on your sprite just to show what Im talking about.
