Judges' comments:
Sharp; in focus where it needs to be; nice light; good documentation photo; shoot from a different/lower angle?
Maker's notes:

The is photo was shot with a Cannon 60D in full sun. The camera was set in Aperture Priority at f/3.5 to shorten the depth of field. Focal length of my zoom lens was set to 20 mm. Due to wind I increased the ISO to 200 to get a shutter speed of 1/1000 second.
