I don't look that much in the gallery, but do agree that there are lots of half nude picture and "sexual" content available. But personally i don't mind that much, its all expression in my opinion. I used to do a lot of classical drawing and doing that it is very common that you draw nude people and a single drawing can take between 1-6+ hours. At first you have to get used to it as it can be a bit strange if you ain't. But its part of learning to draw humans, emotions, motion, weight, proportions etc . I doubt you will find a lot of very skilled artists that don't do croquis or have studied some sort of classic art etc. Its quite normal for anyone studying art. Why wouldn't people complain about all the famous artist, Leonardo da Vinci, Michelangelo, Rubens etc. loads of there art is fully naked people, babies. People getting tortured etc. If art doesn't push people or make them think, enjoy, despise or reflect about it, whats the purpose then?

To me at least art is art and we all like different types. but in the end, the most important thing is that they make people react, if people didn't. Art would be dead a long time ago. :)

And regardless of nudity, would anyone complain about Leonardo da Vinci or Michelangelo for making so many nude drawings and statues? At least i wont, they are absolutely amazing pieces of art. Anyway just my opinion :D
