I just bought this avatar a few days ago. I was told it was the best lynx model, the most fully featured, etc. But now I want to get it modified to look like me (and add my costume, of course).
I don't know the first thing about 3D modeling, so I need someone to do it for me. But asking on Twitter is just going to get me swarmed with bots and scammers, so I thought I'd ask here instead.

I don't use vrchat yet, since I'm still a stubborn Second Life holdout. But at some point in the future I inevitably will. Plus, I was told that vrchat avatars work in Tower Unite, which I do play.

Any pointers in the right direction will be greatly appreciated.
