Thank you for the response.
The premise behind the sprite is a man who has come back from the dead as an amoeba or bacteria. The body is meant to be some sort of single cell organism, the blue thing it's nucleus which is partly hanging out of the jawless skull.
The discrepancy between the body and skull is because I spent most of my time working on the skull and not so much on the body. I had clear concept for the skull but wasn't so sure what to do for the body. I had the general outline in my head but not the actual details. I'll find some single-cell references and work on it. Another cause for discrepancy is that a skull is 3 dimensional while an amoeba is generally perceived as flat, not really relevant to your case since you had no idea what I was going for but it's something for me to a chew on.
As for my color palate, I'm a complete amateur when it comes to colors and my color choices are probably why it's not very readable. I chose most of the colors randomly, especially the nucleus. Not sure why I made it blue to be honest. I'll do some experimenting with the colors as I work on this, although I thought my color choice for the skull was decent but maybe I was mistaken?
and the skull doesn't look that good honestly.
Can you elaborate on this?
