You may not know you did it, but you followed the rule of thirds. For scenics or landscapes, we want to have the horizon follow along the bottom third line or the top third line. If you will take a look at your shot, you will see you followed both.
So good job.
Something that could enhance that image even further is choosing to shoot early or late in the day. This will enrich that scene and add more character.
For a sunset or sunrise photo, you should further play with manual settings. The reason is because a faster shutter time than what the camera would normally choose, will serve to make those colors pop even more. You would actually be under exposing your image.
So the only complaint I have is the time of day chosen. You could also try a neutral density filter to help that sky darken up if you really wanted to do this in the middle of the day when it is brighter.
Over all, good job.
