Awesome sculpting with amazing detail. Would like to see this as a complete figure. I am not a big fan of 3/4 busts.
For me, a bust is a character study. When arms, hips and action are added, it just looks like an incomplete figure to me. Just my opinion, please don't take this as a criticism of this piece as it is superb.
The shield is too thick. Study of small parts is good, but the bust is mediocre - Podorozhnaya not know how to sculpt beautiful women.
I am not sure if you can tell her how to sculpt.... looking at anatomy and stance of your 54mm figure "in both hands" I would think that Podorozhnaya could teach you to improve as a sculptor - as a commenter there is definitely some scope for improvement on your behalf.The shield is too thick.
