Use it for commercial use, for prints, take it outside of DA... I don't really care.
I'll only require two simple things.
1. Don't worry about commenting when you take something, just let me know if you use it, so I can see what you've done and add it to the favorites so other people can see, as well.
2. Add a link back to this account in your credits. If you've seen something useful, or inspiring, let other people know.
Also, if you're looking for something that isn't here, let me know. If it's around, I'll take shots of it and give you first crack at them, then offer them up for other people to use.
Enjoy,
-Lisha.
