1) The sky's highlights are blown out, which is quite a waste, since it does look pretty dramatic.
2) While the reflection is an interesting one, other than that the viewer would probably lose interest pretty quickly. I looked at it, thought "nice reflection" and moved on. Try putting something more interesting in the foreground, have never been to this spot before; so I have no idea. A seashell? A rock? A dead crab? A companion who can pose? Abuse your wide angle to provide an interesting touch to the photograph.
3) Horizon is too 50-50 - not that this is wrong all the time, but in this picture it is especially obvious for whatever reasons, possibly because the exposure difference between the sky and land is so distant that it becomes glaringly and painfully present.
I would suggest getting a Graduated Neutral Density filter, to me they are one of the most essential tools in shooting any sunrise, especially when you are shooting a scene when the sun is already up and blazing in the sky. Also, try a few different angles, find interesting foreground, keep it simple. =)
i thought this is quite a nice shot, conservative framing but nice balance. hope you don't mind but thought i'll just give it a try on post processing, will remove upon request
basically what i've done in postprocessing
1. duplicate the background layer and multiply to ''regain'' some details in the sky, but adjusting the opacity of the lower half with eraser
2. created a radial gradient layer to stimulate vignetting with selective erasing to control the opacity
3. applied a curve to make the picture brighter but maintaining this slightly underexposed mood for the wet scene
4. desaturated the overall a little to emphasize the wet morning and underexposed feel
the original picture is a little flat so the idea here is to increase the dynamic range so that the perception of spatial depth is enhanced, the rest is just finetuning to get the mood you want :cheers:
just like to add a few points..
#1, CPL don't work in this situation here.
#2, for sunrise, sunset, zoom in your lens, or change to spot metering, take metering reading around the sun but not including the sun, best is use manual exposure mode, look at your LCD to fine tune your final exposure.
#3, you can change the WB, to create different kinds of mood.
