first off, the nudity doesn't need to fill the scene.  if you do an image of  a nude female and it's not meant to titillate, seduce, entice, or otherwise make people go, "wow, she's hot. i really wanna do her,"  getting the meaning across without showing key parts of the figure isn't easy unless you a) really emphasized the expression rather than the whole body (see my image "hunger," i think the thumb is actually stronger than the whole) and c) deliberately compromised the pose and composition so that cropping the head without the breasts is easy and doesn't make a really awkward and bizarre composition.

for instance, there are certain places on the arm that if you crop, it looks cropped.  but in others, it looks amputated.  you can't just crop a nude willy-nilly and have it look right.  the less complex the pose and the more derivative it is, the easier it is.  but the more inventive you are and the more extreme and interesting the pose, the less  you can just crop anywhere you want.

heck, even my pretty straight-forward nude studies i don't care that much about cropping. it's my other, more complex pieces i have a problem with.

i had a very hard time making a thumbnail for my most recent image (desolation) cropping out her breast (again, before the ruling).  and i still think it's awful.  i'm very proud of the image (it took much longer to pose, light and postwork than you would imagine), but i think the thumbnail sucks butt.  i wouldn't click on it.  showing more of her torso just looks much better.  i could make it something i'd be proud to post then.  as it is.... i'm already going to have to cut so much from my gallery that it just seems pathetic, so i might as well post and hope some people actually take a look and like it.  and this is an image where i knew what i wanted it to look like from start to finish.  i didn't start with, "well, considering i can't have a thumbnail show a breast or buttocks because that might offend people..."  i started with what i wanted to express and the image i wanted to do that with.  it's pretty easy to just start with what you want to say and end up somewhere out of rendo's present bounds. 

so now my gallery here will be, imho,  incomplete, mediocre and misleading. if i post links to any other galleries, people will be surprised at what they find as it won't be the same as what i post here.

if all i did was pinups, i wouldn't be affected at all.  i know how to make stomachs, legs and other body parts express "i'm hot."  heck, i know how to make lips do that.  which is the point.  i don't see how a series of lips, high heels or other such images would make the gallery look better.  or pinups in bikinis rather than naked.  conversely, the new rule penalizes people who did put more thought and effort into their work, but decided to use nudity.

as for pictures of nude body parts- see mfenberg's gallery, as i mentioned earlier in the thread.  it's gorgeous.  i find it very inspiring.  that said, i've done some illustrator works in that sort of theme, so i also have my own interest in closeups of body parts.
