Okay, regardless of anything, I have to call bullshit on the first part - if he sticks a rapier in someone like that, it's more likely than not going to go straight through them and not do much to halt his momentum at all, at least until the hilt hits them.
Anyway, about the hit before landing,
I added a frame with his foot just one pixel off the ground, but I'm not sure if it's better to actually show that,
or to just imply it with a smear. The first one looks fine, until my eye catches on the pre-landing frame, which makes it feel really awkward.
...Anyway, I'm guessing that bit won't actually be visible given the shake/flash of the hit.
edit: or because I can't stop tinkering with this to save my life,
maybe fucking with the original lunging smear? I watched a video and it looks like the leg kicks out more at first, then lands and bends, so maybe this gets that across better??
