Ah yes mixing techniques uve seen or read and puttng them into practise without mastering the techniques seperatly, not saying its a bad thing definatly got ambition as ur taking urself very seriously, and obviously open minded to take in so many different styles and compare them... I used to do thes same when i was 12-16 i stopped then! By The Time I was 16 i had sparred 3 times wid 2 different Ppl who did kickboxing (dont know what kind) and yes they were alot older and strong than me... But it was only because i was so much faster that the sessions lasted as long as they did... my technique was lame sept for a few punch combos and a couple of meaty kicks! Id say learn a martial art from a pro it helps so much and then learn another, then another if u need to, maybe 2 at once if uve got time. Im not just saying that itl improve ur arts but its great social fun and ull learn alot more (not just the techniques) off ppl u spar, practise with and learn from. Keep Working on ur own style but dont block the lessons u can learn from the world around youll gain Knowledge faster and more accuratly that way
