I feel bad for you, that you haven’t got enough feedback recently. Not forgetting that Vir Norin has given you amazing anatomy criticism though. He really knows his stuff, he has helped me as well.
Anyway, if you’re going to make her animation friendly, I’d raise her arms at least to a 45 degree A-pose, which is still quite relaxed.
Speaking of proportions, if she had feet, she would be 8 heads tall which isn’t a bad thing for a heroic character.
By the way, I’ve used this as a planar reference for a while. It’s quite reliable. The only thing that pops out is the insertion of teres major though. I think it’s supposed to show the posterior deltoid fat pad softening the division between the long head of triceps, posterior deltoid and teres major together.
But overall it gives you the most important forms of the body:
