Mother Brain - Captain N style

[Chris2Balls [:B]]

I really like this, if you could integrate the variation in width of the outline that'd be cool, plus giving it a more cartoony edge.
Much as Ego's sprite is competent I think it needs one more darker shade and a slight change in hue (greener/yellow). The chin does not seem to curl up on either extremities, and the eyebrows aren't quite that shape, they tend to curl more on each end. I'm really liking this so please continue!
