Where do I start? The dark shading of the colors gives the tiger an amazing air of mystery and it's thoughtful gaze excentuates that immensely. The amout of detail, from the whiskers to the tufts of fure on his ears, is clear and sharp. I can almost reach through my monitor and feel this fellow's soft fur! And not to mention the depth which is also shown quite nicely.

There really doesn't seem to be a need for any adjustments or editing in anyway it seems. Normally, lighting is a pain to work with to get it just right by making it not too dark and not too light in ANY photo, but that doesn't look like it's an issue here. I think you did an incredible job at capturing this beast's soul.
One word for this piece: Breathtaking
