HI,
My name is Juls Duncan, and I ran across your 4 elements of earth, and it would fit for a book cover for one of my books. I am the author of the Y/A urban fantasy series, Morgan Koda Adventures. My question is? What are your regulations for using your artwork on ebooks, and Print on Demand? Other than your credit to you on the first page of the books, and a link to your website....
I look forward to hearing from you.
Juls Duncan
