#1 - This is great however we still desire a different look to the martial artist. The hands are more of a Kung Fu style, and while that is nice, we're thinking maybe a martial artist doing a round house kick. We found a great image on Google images, under Images, we entered "round house kick gif" and found a totally blacked out shadow image of a guy kicking. This might give you ideas.
#3 This one is very cool as well, if we could downplay the word "Bend" and size up Martial arts club, and then just have a dragon head and not the full body, that would be a great option.
