I think you did a very good job capturing the figure, the pose is recognizable. Very good job!
I would suggest not being too "sharp" with the shading, instead of lines maybe blocks of grey, if that makes sense.
Thank you for your critique. I was experimenting with the shading. For the last 6+ yrs, I have attended a local life drawing session. In the sessions, I use pen & ink to draw the figure. Using pen & ink there are no blocks of grey. You have to shade using the pen. I can not say I am pleased with the result in this drawing. The shading in the other drawings works better. In this one and others, I use a Blackwing pencil.
Don't be afraid to experiment. Sometimes you win and sometimes you lose. No matter what, do not give up. Keep going. In the end, you will win.
