I've warmed the white balance slightly with this one and increased the saturation in the RAW file. I then made a selection of the eyes and corrected the levels. As for the composition, I think it works. It's a bit different from the cliche of just showing the one moody eye of the tiger that, I feel, has been done to death. I could've cloned out the imperfections, such as the scar on the nose but I want this image to be as close to what I saw as possible.

Apologies for the watermark but this is one image I'm having issues with elsewhere :-( I still wanted to share it here though.
