I used this with some modification (I use GIMP, too - the "clothify" filter is something I like using for texture) for my timeline photo for facebook.
Credited you, of course, and linked. Here is the end result: [link]
Ends up looking like Illuminated Manuscript actually! I'd love to see an Adventure Time manuscript. Not that I'm requesting anything. Anyhow, I thoroughly enjoy this piece. Searched through hundreds of images to find something I really really liked.
Thank you so much for informing me of this and thank you more for crediting me as the original artist. I do like how it turned out. I've been thinking of redoing my tribals recently but I never seem to have the time.
