I'm rarely on DeviantArt these days so new rules are;
1.) Go ahead and use my image for anything personal/commercial. You don't have to tell me, you don't have to credit me. If you'd like to leave a link back to your artwork in a comment or note--feel free! I may log on in the future and I'd like to see what people have used my image for but it's not a requirement, so no pressure.
2.) Respect the model
3.) Don't use to promote hateful things
UPDATE 9/6/2014
This goes along with Rule #3 (now part of rule #1 as of 2023) where I state that I'm okay with commercial use, however some of my stock is taken at a museum and therefore cannot be used for commercial purposes. I'll state this in the description box so there's no confusion. I apologize for any inconvenience, but obviously I have no control over the museum's rules.
Lastly, if you have any questions/concerns, NOTE ME. I am happy to answer any inquiries you have about my stock or otherwise
Ain't no way I'm going through every single picture from back when I used to write my rules out in the image description so just know that *these* are the official rules now
