Without the title I may not have even figured out what this was. The ripples in the water look blocky; I imagine that if you fiddled with the settings for awhile longer you could reduce the compression and still stay under the file size restriction.
The light in this image is fascinating. I love the way it cuts through the submerged boat! It does, however, come off as a bit oversharped near the top of the image--it may be an artifact of post-processing or perhaps a very fast shutter speed... Nicely done and intriguing image!
One of the better jobs of creating an image which is completely interesting, while keeping the main object minimalized. This is a very interesting image to study, yet I continue to be drawn back to the boat Very nice exposure. <8>
I like the subject and feels it fits the challenge well. The horizon seems a little off (but not distracting). Also, the color has a bit of a green cast to it.
