Re: That it works, don't make it good.
Little Black Shirt kid looks like a wimp. His punches were flailing all over.. full of action, but little power. I would have walk right in with my guard up and give the ol' one-two on the gut. When he is down, and winded, I'll prob'bly help him up, offer him a Gatorade (he doesn't seem old enough to be able to drink) and shake his hand, hopefully we will be friends by then.
As for Kung FU guy, yes he telegraphed his intention too early. And his outstreched arm.... ooooh it is just sooooo waiting to be shiho-nage'd or hiji-ate'd.
But hey, what do I know, I am only an arm-chair expert.
