not a fan of 1sec animations, as theyre a pain to give constructive critisism on, considering that ill have to press play 100000 times to actually understand what it looks like.
how can you solve that and make it easier to us?
well, simply make it repeat, therefore i can watch it easier.
iam not sure why his arms ends up behind him after he has made the leap? and it would look better if it were not so symmetrical, I imagine one foot would make the "leading leap" and then the other will follow, not sure how else i can explain this..
his body is very stiff looking, since it doesnt seem effected by the jump at all.
Hands have the same problem as the feet, theyre symmetrical and therefore very booring and unrealistic looking when he is jumping.
hope this helps a bit atleast... I am not an animator myself and you have certanly done a better job than i can do on this, just wanting to help you improve =)
