I love the effects. You really know what you are doing with them. Do not fix them, You are fine on them. Your problem is motions, When the stickfigure leans foreward to charge up his lazah, his leg comes back in a choppy manner. Some tutorials on smoothing motions and jumping physics would help you in my opinion. Focus on human motions for a while, and keep those great effects the same, and you will do much better with this.
I always say in my detailed judgings that you have to look at it and compare it to real life. Do that. I am saying that a bit much though. :P
Keep going!
