You can... unless your highschool is kinda fucked in the cranium... i saw plenty of nude forms back when i was in highschool. also to the guy talking about warhol. there is a great saying...
"Some people look at modern art and say I could do better or i could've painted that... The thing is, they didn't."
also the form in the OP's painting (i know she didn't paint it) is all off tits are part of the form on a torso not on the torso. The tits come out of the torso. also the abdominal section is just weird. This honestly just isn't a good piece. i would never pa for it.. and the color blows.
and comparing it to andy warhol is fucking retarded. Jackson pollack literally splattered paint onto a piece of canvas. simple as fuck. any three year old with a color wheel could produce the same... They didn't. he was the first. And warhol was a great painter for example he painted all of his campbell soup cans separately and his paintings may not be liked by all but still changed modern art drastically. he has a great artistic mind and can see forms well. Jean Michel Basquiat also is looked at as a another modern artist who isnt ctually an artist but its the idea and the style and the personality and the concept of a piece that makes it good. not whats actually on the piece itself. anyone can paint a set of tits. and there will always be someone out there that can paint a better set of tits than you. but if you look at it in a different way and have all the things just right whether it looks right or not it can be famous and world changing.
