Thank you! I think I learned a lot about how different colors work and mix together. I also felt using a palette like this was an interesting challenge rather than an inconvenient restraint.
I did a few different versions of the face before starting the rest of the doll, and for one version I did actually dither in gray and yellow. I think it looks good from a little distance, but from close up I think it looks unpleasantly grainy. Especially with a cutesy character like this, I preferred the smoother look even if it meant a weirder skin tone.
