Hello! Lovely piece! Very classic! I like the expression and the draping of the beads. They accentuate the curve of the shoulder.
I gave you 4.5 stars in vision because I think it's beautiful and well communicated. I also think that there are several deciding factors in my overall rating related to the visionary process.
4 stars in originality, because it's beautiful and classically a portrait. It's classic in pose and the overall simple/complex blend. Very lovely accentuation in the neck, the curve of the back (and the included definition in the shoulder blade), and the semi-contemplative relaxed expression.
3.5 stars in technique and I'll explain my thoughts. You should know that a lot of this is my personal opinion and may be counter productive to the style you were going for. I have seen some of your other portraits and they're all fabulous as is this one. I do feel that you could smooth the shading and highlights of the flesh. Her skin seems like it is smooth and youthful. Perhaps by adding absolute darks, and graduated to the highlights you could affect that. Though her skin is brown and represented by the paper you chose, I think there are some missing complexities that are prevalent in your other portraits. Like the contour of the cheekbones, the brow, and the corners of the mouth. Like I said, personal thoughts mostly, it's just my thoughts on how it could be even better than it already is.
The impact of the piece I gave 3.5 stars because it often ties into the technique for me. I love it, but it doesn't emotionally impact me. (Most portraits don't usually dramatically impact the viewer, so this is not a negative thing) I think that if you were to take into account the thoughts in the technique paragraph, I'd have been more impacted due to the potentially very complex lighting vs. shadow you've got there.
Very lovely piece, I'll continue to browse your page with relish. Thank you, for taking the time to read this and the lovely artwork.
