The 1 Month, nothing to do Mabelma's Project

[Gors]

the problem is; or better yet, your problems are:

1: Too dark. I mean, it's so dark I couldn't tell it was red when I saw it for the first time.
2: Way too much contrast. Look at its hair. It was radioactive green at first, but then it went to swamp green. Hair isn't metal, so it shouldn't have all that contrast. Some hair has shades, though. You need to balance the colors more.
3: Crap shading. Your sprite is meant to be 3D, so don't use gradient shading. Gradient shading, you say? It's when you nake diagonal lines in the shape and simply color each piece with one solid color. This is a very poor way to shade, take your time and try to follow up the outlines more.
4: MS Paint default colors. They're bad for your spriting. DO NOT TOUCH IT, because using them and their darkened versions will ruin your sprite.
5: Use Anti-Aliasing. He's your another best friend when pixelling. It'll make yous sprite loot a lot smoother.
6: Hue Shift wants to be your friend, too. It is not necessary to have it on a sprite, but using it will make your sprite look more interesting.

Phew, that's all. Pay attention into all these criticisms and try to make better. You're really improving on linearts.
