Excellent work! I’m really happy to see how much you were able to pull from Steve Huston’s book (I found it quite unhelpful myself). The cross-countours definitely are the strongest part of these drawings, and I would love to see you try doing some simpler/quicker gesture drawings to practice that skill more. Since your sense for proportion appears to be very good, I would like to reccommend studying bridgman’s books as a good next step for you. Your accuracy and gestural sense are both excellent, but there is very little in your drawings about the way anatomical forms connect and shift in perspective. Study Bridgman, and your forms will surely become excellent!

Almost anything can be understood using boxes! Here’s some simplified family portraits to illustrate the point. Next up: discovering how to reliably rotate these boxes in imagined space!
