It looks pretty good so far, but keep in mind that your descriptors for body parts are just flags. Make sure they have a codex description for when you're looking at your character's appearance.
chitin is the material insect exoskeleton and """skin""" is made of.I'm not sure about the difference between chitin, exoskeleton and carapace.
One thing I've noticed is you put too many flags on your limbs. You don't need carapace if you're using chitin and you don't have to add armored or thick. You could just use chitin for the limbs and just skin with a thick flag so it's stronger than normal. The issue with the skin being carapace is you need joints to move around. Everything with chitin requires joints or to be segmented in order to move. However because your character is partially chitin you don't need to do that just use skin it's easier. Also try to space out the stuff at the top it's a bit much for the eyes. The transfermations are a bit long, try to shorten them just a little. Also make sure you make it so others can look and comment so others can tell you this on your docs.
Memo for myself, Check the stock on the graphics card before ordering one after my old one dies on me.
