Cool bro. I did taekwondo, kickboxing and hung gar.. for a very very brief time Kendo too but meh... Kendo is a sword fighting martial art.. not very practical today lol.
I am tall so kicking comes as second nature to me, but I didn't really learn how to punch/box until I did kickboxing and hung gar. Hung gar really thought me how to be aggressive as it's very offensive... also the training was freaking brutal... work your way up to 30 minutes horse stance and STAY in the horse stance... and then work forearms, punch, move side ways and forward without getting out of horse stance, hold a giant wooden log with finger tips, on your forearms, bounce it around, some crazyyyyy stuff... punching sand/rocks in a bucket...
No one's better at kicks than taekwondo/tang soo do and muay thai guys
Karate kicks being a second imo as far as shear practical brutality.
Northern Chinese martial arts have some flamboyant kicks but eh... they are mostly show.
