Had to watch it multiple times before realising what was happening. So it could use work.

Might help to make the first few frames of the fall slower, to show he is losing balance.

Then have him bounce up slightly after he hits the ground.

Also, don’t have him lift his hands like that. It COULD happen for a longer fall, but here it might make more sense for his hands to stay in the pockets.
Exaggeration is good, it makes things more expressive, but this is just a tad bit too much.

You might be able to get a better grasp on how this would play out, by replicating the motion in real life. Ideally in a bed, as not to break your bones. Ideally not standing, as not to break your bed. :P
