Logo for a martial arts club - dragon theme, japanese inspiration

This is what Unity Martial Arts was looking for in their logo design

I'm about to start my own martial arts club.
My main Martial Art is ITF Taekwon-do, but I have experience in other styles of Taekwondo, kendo, iaido, karate, kenjutsu, so I don't want the branding to be restricted to Taekwondo.
Taekwondo is Korean, but my surname is of Japanese and most of my martial arts are Japanese, so I'd suggest avoiding Korean flag.
My surname is Japanese for Dragon and I plan on the kids classes being called "Little Dragons" so having a dragon would make sense.

The logo needs to be fairly simple as it will need embroidering on every uniform.

Colour suggestions would be red and black. Read more
