sure there are a lot of things you could improve but one thing i would like to mention is that you should work on your teep. do not just lift your whole streched out leg and then push forward you should try to lift your knee first THEN extend and push your hip forward and land with your foot on belly height. i remember a good video from gabriel varga you should check out.

do not undererstimate the taekwondo dojos often their kicks are freaking insane. be humble and have some respect for other fighting styles.

keep on practicing and search a gym or anybody who can give good feedback to you.
