Contrast, Harmony, & Balance

The composition I've chosen for this particular post is this:

It is a perfectly-timed shot of a sunset under a pier. Very cool. As far as the contrast goes, I think the dim color of the pier helps highlight the brightness of the sun, despite it almost setting. Also the contrast between the blues and oranges really makes this something special. It is almost perfectly symmetrical, which means of course it is balanced. The colors, the balance, and the overall feel of this photo make this a very harmonious work.

I scoured the internet looking for a work that I could use and this was the first one I saw that I didn't hate. I think subconsciously symmetry just soothes me.
