First, I'd like to say that all your stuff looks amazing! Great designs on your artwork and great presentation in the photos.
I was looking through your gallery, and this one really caught my eye. So I opened it up full screen and admired it for a bit. Then, I noticed a something that reminded me of a warning a teacher once gave me.
She said to avoid hands when doing a bust/portrait. Her actual words were something like, "What should be a hand resting across the neck could end up looking like strangle attempt."
So at first, I thought, "Oh, how elegant. She's holding up her necklace." Then I heard that advice in the back of my mind, and now every time I look at this, I see a woman about to pick her nose.
Lol, anyway, just thought I'd share my funny thoughts on this piece. *Not meant to be critical or offensive!
