OK.
This animation is bad due to fact that you barely moved any joints in the jump, looked so lazy and unrealistic, atleast try to make it look like a leap rather than a side ways jump...
And as someone said before the jump had no lead up, there is no way he could do such a jump with the anticapation he had, it just looked stupid. Bend he's knee's down some more, then ease it. Add some damn force and reaction.
Something no one spotted but I felt was stupid is that when the camera shifted,"supposedly", he shifted but did the ground? I'm not sure if that was a camera shift or some gayasssupersayen slide action, and if it was, add some trails for effect.
Now, that combo was just awful. It didn't look as if he was punching nor kicking, more like he was trying to swat a fly. The movements were weak and choppy, but the spacing was weirdly nice. Practice some combos and fight moves, and work on heavier spacing (towards the end) it just looked rushed and it came off stiff and a bit choppy.
Haha, those effects were just lazy. It seems most of the times you were meerly trying to hide the awful movements by adding some cheap effect. No dice.
Next time you want some effects remember these simple tips;
-Is this effect needed
-Is this the right effect to use, e.g shape, size etc.
-Am I doing these effects right?
And no, you were not. The starting effect that ball of light was pretty well done, i'll give you that. But those trails...where the **** did they go? Atleast add some particles and make them vanish slowly. Or a better way - fade them out, you should have faded out the lightning aswell, but nooooooooo, just make it vanish. No.
So, that's about it, work on movements, camera angles, reaction, power, physics, easing and effects.
