Poses aren't copyrighted, people. No matter how original a piece of work may be, someone has probably already used the pose before. I've noticed a huge rash of 'OMG YOU COPIED THIS' lately(Hell, even I got nailed with one!)-- but there's a distinctive difference between using a pose, than completely tracing/stealing an image.

I do not mind people using poses at all. Because every artist has done it, or does do it. Either for anatomical reasons, or just because it works for a creative concept. It's very hard to find a way to portray a character that hasn't already been done before.
It's when an artist totally forgoes his own style, and completely rips an image, that there are problems-- however, using a generic 'action/couple/portrait' pose =/= art-theft, or tracing.

I'm really beginning to understand why a lot of people on DA have disabled comments on their work.
