I think my favorite aspect of this shot is how our minds play tricks on us to make us think that the footprint is coming up out of the ground, or reaching down into it depending on what we determine the direction of light to be. It makes for a nice optical illusion.
i love how crisp this is.. and, of course, the flower adds the perfect touch too this, but like someone else said.. too bad the flower wasn't just a tad bigger... though... it is also kind of good for the photo that the flower is so small against the footprint. Gives the footprint more power. To me it could be a commentary on how man is ruining the earth.. not a terribly unique thing to see in it I know.. I"m sure lots of people thought the same thing.. but just thought I'd share
