Hi, being honest, it's a little bet difficult to me to point an anatomy issues becouse it doesn't feel like that's the focal point in the overall composition. But from what I can see, the proportions look good, but particularly the arm and the neck have an unnatural feeling. I'm not entirely sure if the neck would have that look from the position of the neck. With tje arm it's a little bit tricky, looks "correct" but it feels like you were moer concerned about it looking accurate then gestural. As an overall advice, pretty much draw practice gesture from poses of the same nature, (from the back, with the neck twisting or the arms bending) try to apply structure to the point of interest and anatomy studies (always thinking of gesture). Hope this can help you to improve in your areas of interest, as I said, the proportions are good, so try to be a little bit more wilde with the gesture.

Hi James, I think these are great and really expressive, which is cool. If you want to go for more realism I would say the main thing would be to learn the anatomy of the hand. You could then support this great form work with underlying bone and muscle structure. You don't need to know every ligament, just the landmarks and what we can see on the surface ('Atlas of Human Anatomy' by Stephen Rogers Peck is a good book). Structural understanding would not only help with some of your fingers that are perhaps flexing a little further than is possible, but also would help you to draw what you "know" as opposed to just drawing what you "see" Hope that's helpful. It's certainly helping me with my scribblings 😊
