It'd be cool if you make him pull in his legs at the top of the jump, and let him fall a bit faster after that. The jump feels slightly weightless, so he fights against gravity, at the peak his legs fly on a bit and you also get this squashed effect but in the opposite direction, and then suddenly gravity pulls back down, at greater speed than he initially went up. That's generally how a realistic jump works, and if you're going this far in the motion and jump height, you may want to go overboard in expressing these events and create a bit of a cartoony style.
