Nice job on your first challenge entry. During the challenge, I rated this image a 5. My first impressions were that the subject met the challenge but was sort of common, the image looked a little flat, and that it could use a bit more sharpening. For the image presented, the most improvement would be achieved by bumping the contrast and saturation and by applying some USM (Sharpening) after resizing. If your computer has Microsoft Photo Editor, try AutoBalance (In the Image menu) and sharpening (Effects Menu) with a setting of 1. Even with this very basic editing program, you will notice quite a change with just these two adjustments.
Feel free to PM me if you have any questions regarding this critique.
its eyes are a bit soft. For a shot like this, where you know exactly what you want to be in focus, its worth selecting just of your autofocus points (if you have that facility) and pointing that at what needs critically to be in focus. Most cameras will let you select focus, then recompose.
