Dark-eyed Junco

This is a bit of a stretch since it's a very major crop, but the original seemed sharp enough that I could get away with it for web presentation. I wanted to show how the glancing light brought out the red iris in the eye, so I decided to try cropping to a portrait.

1Div, 500mm f4 ISL + 1.4TC, Black Widow head on blind windowsill, f9, 1/250, Av mode with -1 stop compensation, iso 1000. Processed in CS6 and cropped to 2MP. Taken January 3rd at 3:44 pm.

Your comments and criticisms are much appreciated.

Thanks for looking,
