Thats pretty smooth, the back could be bent forward instead of backwards to make it look more intense. Also the back leg seems to be stoped at that certan point then draged along that, try to break it free.
Hard to give any ronk based on that but its looking pretty good, so do more stuff!
i did rush it though walrus, bending the back joint i dont normally do but ill try it... :) i know 1 animation aint enough but ill try my best also im way better than animating on a laptop than computer lol i used computer for this one
