This is where my animated journey starts.

thats pretty good :D

its very good for a first animation, you have good comprehension of easing, force and anticipation, you'll go far with this.
Now the only thing you need to do is to try to make your anims faster.

try to make the arms more free and flexable, dont place it in one place, its like hes chained up. but nice smoothness and easing

I'd say the only thing he needs to work on is loosening up a bit. It's fine to be a bit slow if it gets the movements just right. Loosening should make the jump a bit more anticipated which will look better. Foot placement was a little off so I'd recommend reading this.

this is nowhere near my first animation but thx haah

As said before, the anticipation, force and easing where brilliant.
But you need to practise physics, I don't know about you, but I've never seen anyone stay in the air for so long after such a weak jump.

That, and delete perhaps one or two frames at the peak of each attack and it'd be so much better.
