Its good so far mate. But when he lands on the second block, his center of gravity is behind his feet, making him seem off balance, and it looks like he's going to fall between the second and first blocks. Instead, move his center of gravity forward so he dosnt look like he is going to fall over, yet anticipating the next fall. Also, add some anticipation on the jump. If you look at someone, they always sit back before they sit forward, and then up.
Just get up and jump around a bit, see how you react and where everything goes.
Take care mate
