This is of course Snapai, aka "me on the internet".
I've always meant to have a model of my derg, but this is the first time he's actually looked correct in 3D!
Turns out modeling out wing fingers is nearly impossible with sculpting, they need a prototype built, so while the rest of the body was started with metaballs, the wings were built using splines, then joined to the model with booltools and refined.
Wing and ear membranes are a stretched elastic clothsim, and it looks like that will work in animation as well.

Can't wait to make a rig for him and do reaction stuff on the internet with this!!
