The overall style and feel is.......well......adorable :3
Ahem*, anyway, the smoothness was great, you just have to consider the way a person would actually move when jumping. The clip would be almost perfect if the first half of the jumping arc - from the ground on the left to the height of the jump - was a little faster, and then a tiny hesitation when he's at the highest point. So there's that initial thrust upwards/outwards, the brief moment of partial weightlessness, then the fall back to the ground. Great clip though!
