Ashura's Alchemy Lab

[Gors]

the sprite's face looks squashed. Like, the face ends right after the eyes. You might want to redo some parts of that in orer to improve readability

the metal parts don't look metallic enough, add contrast and bright highlights. Also I think you're using way too much colors in this sprite. Cut some of them and increase contrast in general. For example, look at his pants or hair. It's almost basically the same color.

also his pose is a little tilted backwards, try flipping the sprite horizontally to see any imperfections.
