These are my guidelines for using my stock:
Comment on my stock image to let me know you have used it.
On your deviation put a link to the image of mine you have used.
You can use my stock for any purpose (dA prints, pre-made bgs, websites, etc.) except if you are going to be selling it, in which case please ask first.
I'd also appreciate a fav on any of the images you use, although this isn't a rule since we all have our own faving policies!
