I was surprised that I actually made one, I hope you like it and they are my first.
My first full bodies! I hope they are alright...

Attack Loop

All I can say is that, the stickfigure run loop concept does not apply to full body animation. you also need to learn more about the conceptes of anticipation, action and reaction; which i recommend to learn by using stickfigures b.c is easier and faster to learn the physics. Other than that, you should try a different style other than sketchy lines, but that is just a suggestion, I respect all styles, and I liked it anyway. you did pretty good, keep at it and good luck :D!

The run loop was hard to see, as it was blue on dark gray.
It seemed very stable but it looks like you made the loop with only 1 step.
While this works well with stick figures, the human figure is 3 dimensional and a good run will continue from 2 steps.
Otherwise it's very consistent!

The fight loop is really alright. The only things that could use some work are the reactions of the attacked figure and the balance of your attacking figure.
In short, when he does the first kick there, the balance is off towards the back.

Everything else is really nice, keep up the good work, I'm looking forward to seeing more by you soon~
