You're really capturing the anatomy well and the proportions look correct! My critique is to work on line quality and maybe using longer smoother strokes rather than short ones in places. Also, working on the facial features as well as hands will help!
Marvelous work and job on your contour drawing of the figure sketch, DotFair. Very good work, indeed.
So, if I could provide you with a suggestion, then it could be that though the lines of action are beautifully subtle, but the lines are farthest too itchiest for me. Would you please loosen up your broader strokes with 30 minutes of 2 minute pose sketches?? (15 figure attitudes or poses) (in a diversity, or variety, of dress)
The reason is because, it can and shall be able to help refine and clean up your quickest line quality in your figure sketches.
Good luck to your future and current goals.
