Just a fast combo. CnC please. lol i know the reactions are off.

the legs of the black guy are too long.

A little bit too fast. Its hard to see the punch and sweep.

you lack easing, force, and anticipation.. plus the positions your sticks are in before and after the attack don't really make sense.
looking at some basic tutorials may help you.

yeah, what travis said, and also, try to work on your stick construction too.

Well, having long legs on your stickmen can be considered a "type" of style. I've seen plenty of amazing animations where the leg isn't in proportion to the body.
