hmm. I think it might be better to do the animation without the effects first.
You have a bit of anticipation with him sort of ducking before doing his dash which is good, then he sort of just lands still and the ice effect replaces the leg and does the attack, so you dont really see the little twisting motions of his shoulder and hips or how the arms move while the kick is made. you could also use a little overshot, ease in/out or whatever you feel like makes the feeling of recoil stronger.
I separated the two kicks you say you're using for ya. pick one and try to replicate the movements
Try doing just the standing kick no effects and no dashing for now.
if you need him to get closer before punching, make him step. when you do that think of how that step can be an anticipation for your kick. see how there's no actual kick there but you KNOW where he kicks? that's a lot of why those fast motion blurs in anime work, the anticipation is very well done so the kick is almost a foregone conclusion.
PARTY HARD! XD
i frankestenized the sort of thing you do in animation to save frames, you make poses far more extreme. Think of proko's exagerations in the gesture video. if it looks like a party hard it works XD
here I frankestenized the whole animation, made it far more exagerated and cut it to less frames. When you know what you're doing with anticipation and the line of gravity you pick the exciting moments and mash them together, creating something that never happened but gets to the spirit of the motion in less frames
this is all very much how I do things but I'm trying to say it in a way that emphasizes how I interpret the basic principles. so if PPD or anyone is horrified by how much I'm butching it dont be afraid to say :p
I keep insisting what I show you isnt perfect because it's not just the obviously crappy aspects that isnt perfect, even when I do my best I might get it wrong so that's why I encourage you to make your own observations
