Time to update.
Before I finished sculpting, I exported the model to have some fun with Hair and Fur modifier. Also started making primary, secondary and all the other feathers on his arms.
It didn't go quite as expected...
The later results are better, I undestand what to do with it later.
He looks quite happy here.
Sculpting legs, fingers, etc...
Severely reduced the mesh all over except the parts that will not be covered.
Finished legs
Finished the sculpt. Huge gif inside this one.
Now it's time to to rig it, and then all the other things.
