please post in work in progress animation.
nice try. i think you are beginner. me too. there is no anticipation in the 1st jump, check out the body, make the body and head bent forward before jumping. and the distance for the jump is too much, especially without anticipation. in the second jump the character spins in the air with wrong center of gravity. i am not familiar with quadrupeds. your poses are nice, but make more emotional and powerful poses.
