I enjoyed the entries. Seems like puddles are mostly photographed to capture reflections and there were some great entries of that kind...
Honorable mentions:
Another nice one from Hugh.
Tiny, tiny puddle, but still a fun shot.
That's one psychedelic puddle!
3rd place:
A veritable puddle-scape.
2nd place:
That's an awesome selection and the colors are also great. Those iPhones take pretty good pictures!
Winner:
I like black and white images. This puddle was use for both reflection and distortion, creating a dream-like effect.
