i made this animation today and i don't know if its ok or not. you be the judge.

Truthfully, it sucks,
First off, before you try to do effects like that beam you should master the basic movements like walking, running, jumping, punching, and kicking
Second off, try not to use the default stick figure, since you're not experienced enough to make one yourself go onto droidz.org and search for a "base"
Third off. its stiff, for now try to move every joint every frame, it doesn't have to be a big move but it looks unrealistic without doing that
Fourth off, You need to understand "easing" since i can't find a decent turorial at the moment, and am way too tired, i suggest using google, google is your friend
Lastly, its choppy, try not to move from one pose to a completely different one, try to ease into it
BUT if you keep on practicing you will get alot better
