Hi Shane - A very nice first sunrise image. If it were mine I would try to bring out a little more detail in the clouds through LCE and luminosity masks. Another thing to try in the field is longer exposures to blur the water and capture the movement of the clouds. Use a tripod. There are all sorts of fun possibilities if you have regular access to nice sunrises and sunsets.
Hi Shane, you are off to a fine start with your landscapes. If you are not opposed to doing so I would be tempted to clone out the ships. And for me the dark sections of the clouds seem a little too blue...you could fix this by going to selective color and select blue and then reduce the black slider. Rachel offers a good suggestion for bringing out more detail in the clouds. What are the lines in the water in the lower right area of the comp?
