Jump and Roll animation blocking

Hey again! Just though that I would post another animation I'm working on. It's done using the character "Stu" that was given out to the Animation Mentor students. It includes Stu leaping out forwards and ending in a roll. This is just the blocking right now so still kind of rough. I'm just trying to figure out the timing, and see if my poses are OK. As always if you've got some time, feel free to check it out. Any comments are appreciated, even if you don't know anything about animation, you still might see something that just doesn't look right to you. Go ahead and tell me!

Jump and Roll

Thanks.
