Well, you definitely have experience! But it really depends on what qualifications you have. It seems to me like you would do really well in a music teaching career, though. Good luck :)
I'm from Malaysia, am 17 years old, I teach 4 instruments which are piano, violin, guitar, and ukulele, I have teaching experience too. I would like to know, am I qualified to teach in the UK in the future? :)
With that experience and knowledge, in the future, you should be more than capable to teach anywhere you choose! Good luck to you! :)
