Need I remind you that there is a difference between the following words. Proceed to read the definitions if you are not already aware that there is big difference. Nudity isn't sexual. Nudity should not be censored and sex should not be feared as a subject matter and part of life.
PORNOGRAPHY - creative activity (writing or pictures or films etc.) of no literary or artistic value other than to stimulate sexual desire.
EROTICA - literature or art intended to arouse sexual desire.
NUDITY - An unclothed human figure, especially an artistic representation.

There are some things that are backwards, some things that are censored that shouldn't be, some things that are not censored that are more harmful and permanent than any nude photo or even cuss word. Nudity isn't sex, and as for sex, we are more comfortable with children being okay with war than okay with sex.

I was recently at the local Half Priced Books, purchasing a book from the Art section that was an artists reference for nude models and figure drawing. I get a remark from the young and ignorant cashier. He giggled and gave me a sarcastic "Oh what is /this for?" I replied, unamused "I draw. It's for drawing references." Only to get a "Hehe, okay then!" I could have pretended to be confused, but I didn't. This confusion is a pet peeve of mine. I called DreamRunner on the way home and we discussed the situation. I was a little furstrated.

To mock the situation and get to my point even more, any anyone who thinks this way, really, I re-worked the painting "Leda and the Swan" [Third image down:http://www.en.utexas.edu/amlit/amlitprivate/texts/leda.htm ] by E. Pontormo, he himself was openly influenced by Leonardo.

Which touches on another point. This is a 'rip off' right? It wasn't traced, and it was cited.
There is no 'unoriginal' or 'orginal' art, atleast not that will get you in trouble. Trends and copying are part of art. Look at the works from the 1400-1600's, people knew what worked and the learned from others and copied others techniques and subject matter and even painted over very early versions of photos, flat out tracing photos that they didn't take and called it theirs after a layer of paint was slapped over it. They repeated overused poses, they messed up on anatomy, [next time you're bored red-line a photo of the statue of David with normal human anatomy] they did everything "wrong". That is just part of art, I obviously need to point out that it always was, so CHILL, when someone copies your art, as direct or indirect as it may be, it means nothing more than they are copying what they see clearly working well for others.

I hope that benifited you. I'm back in school, and trying to get back to meaningful art, hopefully with a good message and sarcasm..
