Seriously ambitious pose. Great work! The things I notice in the line work that may need adjustment are: the connection of the bicep and extensor flexors of the forearm; the upper thigh into hip feels a touch narrow making the torso a little long; and the right leg’s feels like it needs to be read a little more from above. Is this from imagination? It’s terrific. The notan lighting source appears to be the viewer, I feel like it may read little more of the dynamism of the character if it swung a little further to the right or left, but that’s just being picky really. Impressive work.

Nice work.
