Sparkledog designs for a comic. Coloration rules are four colors, one of which must be either a different shade of another color or white. I'm trying to keep them bright, facially expressive, and easy to draw, since I'll have to do it a bajillion times.

I will not be doing body type variation for the five main characters. I want the reader to identify with all five povs simultaneously. Differentiating them in a relatable way will encourage the reader to pick one over the others. Hairstyle will not do that, since not all the characters have a mane, the style is vague, and hairstyle is usually an alterable choice.

Please offer suggestions and critique, if you have it.
