I saw a very cool reference pose posted on The Male Form, and I wanted to draw it:

I liked the interplay between his feet and hands and the perch he's perched on, and I especially liked the flex of his frontward calf muscle - I liked that you could see both an almost-straight shin in front and the way the somewhat flattened calf muscle attached. 

I could profitably spend more time on his toes, I think, and his face, but on the whole I am very happy with this one.

In my imagination, he is about to leap forward into the water, but wants to make sure someone's watching - he deserves an audience haha.

Thanks for looking!
