Where could I learn this kinda stuff?

Jumping up and kneeing people in the jaw/nose; Jumping roundhouse kicks (as in jump, 360 spin, kick them across the face and you come 'round); Quick 360 spin, kick them in the stomach then the face when they double-over; Kicks to the temple. Just various, high-flying kicks like that that look flashy but are very effective as well. And they also allow to take on multiple opponents at once and opponents that are twice my weight.
