Final Fantasy: Mutant VI

Good start. The shape is generally good, and the tail looks better (though still needs to be smoothed out a lot). But the shading is... confusing.

My suggestion would be to go through and make everything monocolor. Get rid of ALL the shading until you have a solid red costume, solid lighter blue skin, and solid grey-blue hair (leave the outline and eyes as-is for now). Once you can see all of those shapes clearly, THEN go through and try to add darks and lights to the sprite.

Actually... once you make it all monocolor, post that here so that someone else can add shading to it and give you an example, maybe? You can certainly try it on your own too, but if you add the monocolor here and make it easier for us to help, we're more likely to.
