If you want to use this photo is my rules simple:
Use my stock photos as much as you want for photomanipulations or other artwork on DA and on other sites. You don't have to ask.
Please send me a link to your work if you use my stock and credit me whenever you can.
Don't claim my photos as your own.
Ask first before you use my stock for commercial purposes.
That's it! And of course: Be creative and have fun
