Seriously... get a life you pompous ass. Art is creation in any form; the boundaries, rules and standards for "Art" are ridiculous... because there ARE NONE!!!
if you happen to be better at painting than someone, great, paint, be marry; but don't try to tell anyone they are wrong about something in their art work, if it's right to the creator... it's right. unless you are in it for the money...
of course if you are in it for the money, it's not artists or people who appreciate art who are buying it... it's high class snooty bastards that have people from some historical society telling them what is good and what's not....
