C&C per req:
1. A couple of issues with this image: One it's desparately in need of straightening; all the water is about to run out of the image and onto my desk! The next thing is the exposure; you have blown highlights in the foreground and LH background and full black along the shoreline. I would suggest doing your best to fix the exposures issues before conversion. The conversion however isn't bad. You've got a good tonal range, and I suspect that with a better exposed image to start with, this would have turned out nicely.
2. Minor exposure issues with this one; you have a blown LH edge, and full black RH edge. I would suggest cropping a bit of the left, and about 1/3 off of th eright; that will leave you with a nice sky, a good silhouette, and nice detail in the water.
3. Once again the exposure is somewhat off; is your camera by any chance set to 'Spot' metering vice matrix? This image is also leaning somewhat to the left. With respect to the composition of this image it is a bit busy; I think perhaps it would have been better just having the two fishermen in the foreground and the water/breakwater in the background, but not the boats you see to image right.
Just my $00.02 worth - your milage may vary.
