Seem’s really cool, my 2 cent is more hair and clothes (this provide something that doesn’t exist on the marketplace for a character creator system… is hard to create hair or clothes), your customization seem’s fine to me with the preset, if you can provide more starting clothes and hair (and also sell it in a different package) will be really awesome for me. Also is really important to create different looking character, but from the video seem’s really possibile atm.
This is surely the right approach, i’m really hyped.
Really a nice work, really interested in buying this when i see some clothes.
It will be cool also some physic on breast 
Just one question, is possible to create a character without using your editor and change the clothes and hair on demand? (like a prebuilded blueprint character that can change only some parameter on demand)
Also buying on gumroad will give me the updates? i never buyed from github
