Running girl copy picture

A picture that I copied from my Megami magazine with my friend to see who could draw it better.

Sometimes we copy just the pose and draw any character in that pose, but this time we did a straight copy using a skeleton with guidelines. The only problem is I tend to keep picking all the impossible to copy pictures, so we always find it really difficult.

By the way, this is a copy of a picture, so thats why it looks way better than what I can normally draw.
