if you wanna call something simply "a painting, a drawing, a sculpture, a photo, etc," what you do is you fall into predefined monikers that have existed for god knows how long, sometimes centuries. The best thing you can do is to say "fuck those", and make your own, or just say it's "none of the above". The moment you create boundries, you limit yourself. If you're going to limit yourself, what's the fun in making art when half the fun is breaking the rules?
