I'm guessing you digitally painted over your photo? What a fantastic result! At first I thought you simply applied Photoshop's Surface Blur to get this, but there's too much character in this and I think I see remnants of brush strokes.
There's a clarity to this that I really enjoy. If it was at a slightly higher resolution, and if I was the type of guy that used flowers for my PC background, then I'd use this as my desktop background.
