I check this very infrequently. So I'm sorry that there was a back-up of messages and such. DeviantArt has changed quite a bit since I've began, and so I've decided to make some changed concerning my stock rules.
I am going to test out offering some new images for fees, where you can access the full-sized original file via $0.50 download, no credit on the image necessary when you modify it. If you've appreciated my work, please consider doing this with my new images that I'm listing. I'm going to see how this goes over the next few weeks, and then make more decisions concerning my stock after that.
For my non-watermarked stock, here are the rules:
1) Please credit me. On the image (if off of DeviantArt) or in the comments with a link to my page (on DeviantArt).
2) Please send me a link to your creation, either via note or commenting somewhere on my page. I love seeing the results of your work.
No need to send me a message if you want to use the image on a SIM game or any other purpose, just follow the rules above.
