Only managed the wings and how they are connected to the body so far.

This took so much of my energy, that I’ll have to take a break now. Maybe later I will be able to get some more done, but I’m not sure about that…
Funny how sometimes something small can take forever to solve!
I used a UV Sphere as the end of the wing and it turned into an oblong shape as soon as I used a Subsurf on it: not round but oval!
Tried to solve that for hours and still don’t know why that happened. Used an Icosphere instead and everything was normal.
This is a mystery that will keep bugging me;)
