I did this animation in one week, and received some criticism on my camera angles. I could have done it from another angle to show his movement better. When his body is falling right before he is takes a breath is head should be down more to show this movement and exaggeration. When my character turns his back is bent a little too much. To fix this I can bend the bottom parts of his back more so the top half bent is not so extreme. The arms are moving at the same way in the end, offsetting one would make it feel more real. When my character is taking the deep breath it should hover at the top more, giving more anticipation. Also through the animation you can see his elbow snap forward. My characters feet are at a fixed angle when he kicks them out, so maybe rotating one a bit would help more.
