Yeah, I quite like the animation, but I tried out some shading and stuff for the background. Bear in mind I have next to no artistic skill whatsoever.

The bg was ok, but could be better. Maybe add some cracks and stuff to the mountain, and just don't do the bird. Or do it, but get a LOT of advice that I can't give you.

Hehe, come to think of it, what started out as a background project didn't actually end up with me spending much to on the bg at all. I just saw the cliff shape and decided to throw someone off it. I'll try adding some stuff to it tomorrow.

He fell to slow. He should gain momentum as he falls.

dont make the back foot go up in the fall at the start for then to come down again it just seems akward (i dont even know what it means:D sounded cool)
and the background was awsome (i think) but their is'nt much to say bout the anim

I like the BG how it is. It gives a lot of room for the animation to play out. Better that way.

The easing was good (but,... it's just a [SIZE="1"]tiny[/SIZE] bit slow).
Impact was nice, and yes, the falling was way too slow.

The descending speed was the only minus for this anim.
Though, you should have added more, like him falling off of the rest of the cliff and have him scream,.................. then SPLAT.
