based on topic poster.
really nicely execute study. If I had to offer some constructive critique I'd say you could strengthen the C curve that makes up the gestural line in the figure. The figure in your ref has a bit of a stronger arc. You can see in the way the back of the heel and back of the head are on the same vertical parallel. Likeness is very well capture tho, keep it up.

Finished inking this last night. Gonna try and use shading similar in execution to an artist called Thirty 8ght.

Might soften up the busy line work on the dick before I proceed tho.
