Doesn't appear to be touched much. Altered colours, brightness, contrast, shadows, highlights. Added blured layer, anywho, I like how it turned out.
Are those all the layers, or different versions? Anyways, i'm guessing the last one is the final, and it's pretty good. I like the colors, and i think it's very simple in a good way.
Thanks. The final is my current sig but I went back and altered the tones, etc. for different versions to see how it'd look.
