Color choices are great. The design itself feels a little bit tribal? Keep in mind the site is about martial arts and it's positive "vibrations" as you said.... but it's also about the health benefits, it's about discovering a place/location to experience martial arts, and it's also full of testimonials/information to learn more about martial arts. Does that help strike any more inspiration? We've seen a ton of martial arts stick figures - and if that's the only symbol that depicts martial arts we are willing to entertain those ideas, but we are hoping an unbiased artist such as yourself can depict another icon that captures the spirit of martial arts without seeming too cliche....
