Pup,
That's a nice sunset, but I have two criticisms, one minor and one major:
- The minor one is that the horizon isn't straight: it needs to be tilted a bit clockwise.
- Looking at the exif data (f/5.6, 1/3 sec, ISO 1600) I'd hazard a guess that you weren't using a tripod. You can't really do shots like this without one, IS or no. The foreground is OOF and the in-focus distance is motion blurred. This shot would be a whole lot better taken at f/11+ (so everything is sharp), ISO100 (so no noise), and a loooong exposure (the water gets nice and milky). And on a tripod (so no motion blur).
Otherwise, it is a well composed and well exposed shot (although I would perhaps taken it up a stop or two and then played around with the tone curve in Lightroom). What is lacking is the technical execution.
Please take this criticism in the spirit in which it is intended: you are a learning photographer (like most of us, just at different stages) and I am trying to give you straightforward constructive advice.
