I think you got the body structure and the lines right, however, I think you missed the mark a little on the muscle development when you cut the lines in. All of the places where there is a line, there should be a topology elevation difference. The colored version works a little better.
Completely aside, it is odd that the coloring on the hands is on two different sides. Not sure why the artist did that.
