With the exception of the two pair of wings, for the general shape I got inspired by scansoriopteryx, a genus of dinosaur that evolved for having wings similar to bats. And dragons!
Well, I started this model last year, during the CGMA course "Sculpting Anatomy: From Animal to Creature". I was very happy with the model but not with the final result of the render, so I decided to give it another try. After learning a lot of look development I finally can conclude with this tiny fella!
