Listen up people! I say that there should be a category for MARTIAL ARTS in deviantART.
There's a reason it is called martial ARTS, and that it is because it is a creative form, much like dance, mime, and theatre. The category could be set up like so:
Martial Arts> Hard>Forms
See? Now if you take into account original techniques, or original uses for techniques, then martial arts can easily be considered an art form. Everything was created by something at first, so why should it be different with martial arts?
Finally, I'd like to say that doing this would open up so many new windows for the art world. Thank you, and please help this to happen!
