The left eye (right eye facing you) was very dark. I
selected it with the lasso, feathered the edges 3 pixels, and used a
levels adjustment to lighten it.

Converted to b/w with DigiDaan b/w action.

Also used a shadow adjustment in PS CS to bring out more detail in
the fur...then a 10% + contrast adjustment to give the image
more "pop". Ended with a bit of unsharp masking to crisp it up.
