This is amazing! I was almost positive that it was a photo! My hat goes off to you, that isn't something I think I could do in a million years even if I practiced non-stop that whole time. Feel free to take a bow
At first I found it hard to believe that this was a painting, but, looking closer, the only things that even remotely said otherwise would be the ear and the hair on the left and maybe the bangs on the right(the forehead seemed to be missing from under the bangs, but then the colours in the photo probably showed the same lighting quality diffusing the shadows beneath with the colour of the hair), and again I say that those areas are very well done. Maybe I just needed to find something that would make me feel better about my own limited abilities. Absolutely amazing painting, well done!!
I did a double-take on this one...I truly thought this was a photograph for about 5 minutes, until I took a small section and convinced myself otherwise. ^^ Amazing job! Your wife is very beautiful, too
