Nice work, Marlonjohn! The hump action in particular is very convincing (if crass, but who cares! :-) ). The back flip is very nice too, but a character backflipping would not land in the exact same spot! Have the character's feet land a couple of feet behind where they were originally planted and I'll wager it looks a lot more convincing! Again, the basic action is very nicely done!

I do hope you will share more with us as you finish it!
