Photoshop is a very important tool for the digital photographer but, having said that, you should try and make the best image possible in camera, and only use PS to enhance good shots and not to fix bad ones. Here are some of the key edits to consider applying.
COLOUR The green shadowy area in the bottom-right corner was a bit distracting, so this was edited first. A new layer was created with the area erased out, then the background was selected and adjustments made using Color Balance and the Dodge Tool.
LEVELS A Levels adjustment was used to lighten the image up a little.
SHARPEN Although both the bird and peg are in sharp focus, Smart Sharpen can be used to enhance details.
CROP The last step was to make a small crop while still maintaining the original aspect ratio.
