I love the contrast you made with the figure against the background as well as the choice to leave in the line work. Overall, I get a strong sense of light where we want it and shadow where we want it. A good painterly effect with the broad, loose strokes. I did a little paint over where, in my opinion, softening the edge between the triangle shape between the arm and the arch of the back reduces the contrast there, creating less of a draw for the eye compared to the face. I also brought the light shape in the background down a bit for some asymmetry but also to separate the hip from the background is it comes forward relative to the other side. This helps sell the idea of the slight turn in space, with the other hip fading more into the background thanks to that heavier line on the contour. See also that I darkened the feet a bit more to reduce the sharpness of the edges against the floor. I hope that makes sense.

My feedback for you. I think there is nothing to worry about your value structure on the figure. Lightest shadow is about halfway from the main skin value. And your halftone is close enough to the light value to not appear as a shadow. Maybe the halftone in the screen-left calf is a bit bright so creates some distraction there. But overall, great use of texture for softening edges. Ah, there is one thing about the shadows of the face. Around the eyes that shadow is a touch too close to the halftone values. Step it down into your shadow range and soften the edges on the lower site. Some proportion issues in the arms and pecs but this is not an anatomy course so meh. One additional point to consider is the background. The overall dark value is too dark for the figure and creates a really stark contrast that flattens your painting. The light patch tries to bridge the gap but the black is too dark. Step it up to somewhere near your darkest shadow but lower than it. Then consider the fact that on the reference the screen-right side is in shadow while the screen-left side is lit. See what putting a slightly darker value on the screen-left side and a slightly lighter value screen right. There will be a separation that you can play with where you want to bring the forward hip forward and the slight back hip (screen-left), will be behind. Have fun and keep it up!

beautiful!

Great study!
