Here are some more cork portraits: http://www.visualnews.com/2011/08/27/beautiful-portraits-made-with-old-wine-corks/
What lens did you use? Background blur looks a bit strange to me almost like it has been selectively blurred in post!
+1 Great eye... the trees below his left ear and above the collar were missed out in the PP blurring.
You said Cork Portrait, and I thought you meant cork portrait. EOS 5D Mark II, EF 100mm f/2.8L Macro IS USM, 6 s, f/5, ISO 100
I like the effect / exposure / colors. However there's something about the framing that is a bit distracting... can't quite put a finger on it... (apart from missing part on the sides).
