I decided to go with more natural skin-tones and hair color, partly because I think switching to the pastel colors in the bimbo forms will be more impactful, but mostly for convenience as all those different hair colors are a pain to model.
First I'll be doing before-and-afters for the different characters, and a group bimbofied shot by the end. I think I'll do bunches of other MLP characters too, but not for a while after this first batch.
