Such a tiny picture! See the tutorial on this site if you need help submitting photos at a bigger size: //www.dpchallenge.com/tutorial.php?TUTORIAL_ID=26
Good find. I feel like the overall picture is a bit small though. It would have been nice with a little more contrast to really make the shadow stand out.
Accidentally resized it too small. ;-)
Most common tip on DPC: Make sure the image is close to the maximum size allowed (640px on the longest dimension). Not to be mean, but the size ruined what would have otherwise been a nearly-mediocre entry. :(
