I think the piece is really nice as well.
A few things I think you can add are:
Cast shadows from the bracelets onto the arms.
More of that blueish white light onto to face. She would need some more reflections on the eye's
You can also make the reflection on her lips a bit brighter as well. The bottom lip catches light a lot.
Other than that, really nice work. I really love what you did with the cloth. and the background color change helps a lot.
@cedricgo said everything else.
I also wish more people would give feedback as well, but, what can you do when some people are either shy, don't want to be or sound wrong or any other reason that i can't think of.
Keep up the good work. Look forward to seeing more.
