Just really two things that I personally would tweak about their creation process.
1.) Horns and Faces: Horns and faces should not be tied in together. They should both be separate categories. I've run into quite a few people both in my FC and outside of it, that like a certain face but hate the horns attached to said face. Making them separate and each in their own category would solve this which would aide in more playing the race or even Fantasia potion purchases.
2.) Body Scales: Add a feature in the features tab portion to toggle the body scales on and off. You could do it as a simple toggle for all of them or toggles for arms, chest and legs or as NorthernLadMSP said to put it on a slider 0 being none with only tail and horns and 6 being full coverage.
I will try and actively edit with constructive feedback.
