Also I had drawn some scenery background, subsurface scattering/back highlights effects/feathers/non-trivial eye highlights. Seems, to much for first time without training. Mane/hair drawing is still mystery for me.
I see a huge number of mistakes in this picture, but don’t known which is most bothering for viewer’s eye. So I appreciate if you say which mistakes are most annoying, and which technique should be practiced and improved in the first place.
