Good Work @Art Anderson, practising gesture drawing and basic form can be helpful.

Art; Good on you for tackling such a weirdo pose! This is so lovely, with the line drawing lacking any shading, it really has a great deal of correctness with a very few little deviations. Head is too big. Curve of torso slightly off, and that makes the torso less balanced than in the photo. Rib cage is smashed into iliac crest on the right and on the left, the angle below bottom rib is more acute than photo. As has been said, left foot needs to be planted on the ground, not on tippy-toes showing all the toes in same perspective. Negative spaces so carefully done they mostly match except the angle of the spear. Yours is tipped at more of an angle relative to photo. Right hand is slid out toward the butt of the spear more than photo. Entire right leg looks too muscular to me but I was thinking that was due to the careful line drawing without shadows to quickly tell the picture plane. But, even looking again, it seems the right leg is just too wide. Lower leg on right looks perfect, but thigh is showing different curve. With the gesture so correct, it masquerades as perfect, but it still is sort of...not. I believe the photo shows a more convex curve on the left side of the torso and that is where the gesture goes haywire. Pit of throat on your guy is back further than photo, which leaves it looking balanced, but not the same as photo, where balance point is more forward. This is JUST because you asked, and different set of eyes and all that...I think you captured the majority of this living pose, and other than size of head, your drawing works. I share your wish to improve and feedback is the breakfast of champions, for that. Without direct feedback, my eyes just gloss over my many, many mistakes. Even when I am looking to improve the faithful capture of the figure, or face and the tiniest little angle-goof is glaringly obvious to someone else, I won't see it. I'm looking forward to feedback myself. You got so many areas spot on, in such a twisty-spiral pose! What happened to the hands? Did you get bored with them? Beautiful work, really.

If you mean the figures left foot, than i think it looks more like the figure is on his toes --> just plant the heel to the floor and i think you're good. The other foot flows quite nicely. With such a dynamic poses, practicing gesture drawings fixed timed sessions may be helpful to get the read on the pose right and then follow up with detail. Keep up the good work!

Hey there! I'll share with you an amazing trick that can help you improve fast. If you photograph your drawing, you can put it in any image editor and then place your reference over it. You would instantly see where your proportions are wrong and what to fix ;) For now, what I can see is that his head is too big, the torso is a bit squished, his arms are a bit too short and the shadows are not following the form. To get the shadows right, I recommend checking out core shadows and ambient occlusion, those are the most important to define a figure well :) Hope I could help! Keep up the great work! :)

Hi!. You could try to draw the foot as a simple shape with the correct perspective first and then put in the details
