I tried to practise bird anatomy and to do it well, for now I only chose one genus - Carduelis and drew some of its species from several diffent angles and in positions rather hard to draw. Uff, I remembered once more how difficult the birds are to draw... and how I hate their feet ... But it was still fun I'll try it again
A-mazing! Your sense of anatomy shows in all of these, they're just spot on! Feet indeed are a pain in the ass to draw, but you've manades really well here (especialy on the bottom left and bottom right) I can only bow down before your bird-drawing superiority
