Your details and highlights are fantastic, and your style is so unique. I would love to see you push your rendering further so it's more consistent throughout the entire piece. I'm getting very distracted by the proportions and placements of the mouths in each drawing. I don't know if this was a style choice, but it does lean more caricature. If this was the objective, then well done, but if not and you are trying to land a bit more realistic then I would measure your nose and mouth sizes and placement so they are scaled properly with the other features. Hope this is helpful. I love your work, and I hope to see more!
I love how you're building your forms, you have a great understanding of dynamic movement and the volume of the body. When incorporating perspective you might want to give a bit more attention to the skeletal structure and proportions of that structure within your planes. Then build the mass of the body on top of that. Really gorgeous gestures though, I love how you use your line. Very expressive. I can't wait to see more of your work, you're clearly very talented.
