it was featured in several writing prompts (poetry) I think the writers did look for the artist (you) but I suspect the picture has made its rounds on Pinterest first as that is where a lot of twitter posters pull their material from. I hesitate to name anyone in particular as I don't know who used it first.
I used it with a poem as I was unaware at the time that the prompter had no idea who the picture belonged to/did not have permission to use it., I have since pulled the poem/picture off the net,
I can say that this picture was very popular on twitter for the last month. I just like to be thorough when I am writing on the net. I would love to use your art in my own work, I have asked other artists and photographers. So I am curious how you would feel about that idea. If that would be permissible- I would leave credit on each post along with hyperlinks and info on your work/site/etc. I will only repost it if I get your permission to do so.
I can send you a copy of it if you wish to see it first.
