Sports Bunny

I wasn't satisfied with the way Lola turned out in my previous picture, so I knocked out a few more drawings of her. This time I tried some sports poses that I saw in other sketches to get some practice with various angles. Despite everything, I STILL can't seem to draw her properly. *tears hair out* Only the middle pose is close to her official appearance, but the other two are plain rubbish. (I shall say nothing of the generic, recycled background.) If anyone cares to offer any pointers, I'm all ears.
