It looks like another picture I have in my favorites. The mouth, lower face, that shoulder, definatley looks like another picture i've seen. Done by a pretty incredible photographer, so, it would be shame if you copied it.
yes I did use a reference pic, no idea where I did find it, but if you say it looks like something you favorited here...that could easily be the case, I got inspired by deviantart works for years now, but only joined 2 months ago. I never knew this was a crime, it's not like I used the original and changed it. But I do agree, the photographer is pretty amazing, and I will look him up in your favorites and and write him a note, asking for permission. I had people drawing some of my work and I always felt honored. But like I said, I had that pic saved on my comp in forever, and didn't know where I found it.
