Hello,
I've located a larger version of the image with EXIF (attached). Seems it was taken with a Canon EOS 5D on January 6th of 2010. Unfortunately, no copyright information.
There really are a ton of versions of this with writing on top! Strange that so many people plaster inspirational quotes atop the picture but no one bothers to explain who the model is, where the picture came from, why it's special to them, etc.
Anyway, good luck!
EDIT: I think I've found the artist: Rudolf Kartelin, a professional photographer from Russia.
I found his image on a Russian forum and the poster identified Kartlin as the author in the post. SFW screenshot:

I looked through his portfolios on a couple of photo sites, and I couldn't find this exact image, but he does have many other shots that look painting-like. Overall his style is a little different than what I expected from this shot. I (and whoever posted the picture on this Russian forum) could be wrong about him being the author; you could always PM Kartelin on photo.net and find out!
He shoots mostly nudes, so
