All-Star Bow And Arrow Help?

[danielliebear]

I need help going from my heelstretch to my bow and arrow! I have a pretty decent heelstretch, but i'm not understanding how to get my leg to the side to put my arm through. I'm not sure if I just don't have the flexibility, or if i'm doing something wrong technique-wise. Could I have some pointers? :)
