Here are the rules for usage of my stock:

Credit me

Note me with a link or post a link on the original photo

Ask me for permission to use my stock for prints

You may use my stock for non-commercial contests here on dA as long as I'm credited

You may not post my stock on PhotoBucket, Imageshack or the like. You may not use it for tubing, brushes or the like.

Ask for permission if you want to use my pictures in blogs, in the creation of an rpg avatar, layouts etc.

I do NOT consider change of hue/saturation, altering to b/w, minor changes such as dogding/blurring/burning and simple usage of brushes as manipulations. Please, be creative with my stock

Do NOT use my stock for creating more stock (e.g. manipulated backgrounds)

Respect the models

My model stock may not be used for extreme violence/gore pictures, pornograhic, political, overly religous, racist pictures or the like. They are humans, they have feelings.

I do make requests, but no nude/fetish pictures
