If you want to use this photo are my rules simple:
Use my stock photos as much as you want for photomanipulations or other artwork on DA and on other sites. You can of curse use it for DA prints. You don't need 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 any bigger commercial purposes.
That's it! But most of all be creative and have fun
