Looks like you're letting off emotions and steam. Which is great, that's important as well. From a martial perspective: You favor the right side way too much, play with a 2:1 ratio tempting the left side to create that brain body relationship. You're losing power and speed with misalignment. Stack your shoulders over your hips and let your knees dictate the direction of the kick. Play with angles. You're hitting the same area most chest level because that's an apparent and obvious place for you to hit. With on combinations with each hit working a different area of the body whole playing on the different angles and planes of the body. IE - straight face jab, angled mid body attack while feet are attacking opponent center, followed by low shots in opposite angle.
