*Update* So anyways I've been getting alot of backlash from using a referrence photo and not crediting the person. And again I apologize for not crediting the original photograph.
That said, I did not simply doctor the photo.
I attempted to recreate the original photograph through digital painting.
Here's the .psd file: http://www.newgrounds.com /dump/item/31da412edcbfe3 97366a0db30a65270d
