Chris has it. I can see a bunch of things I could critique in your execution of the self-defense sequences, but without knowing what system you practice and how your instructor wants those techniques to be executed I might be steering you in the wrong direction. You're clearly somewhat of a beginner in this system and your instructor may have specific priorities in mind for refining your technique. (If you were my student, I'd have you slow down and work more on the details of maintaining your own balance and controlling your opponent's movement and balance. Your instructor may have a different approach.)
As far as the kicking combos go, I would place a higher priority right now on throwing each individual kick with the best form you are capable of. I don't know what form your system advocates, so I won't offer any details beyond that. If anyone here practices the same style you do they might offer advice, but they might need some better camera angles.
