I feel like this is a simulated HDR or a Photoshop filter gone wrong. The colors are awesome and I like the extreme differences between the foreground and background. But there has to be a focal point - a photograph shouldn't be out of focus everywhere.
Using a tight aperture can give you a dramatic effect, but if you don't focus on something in particular it can keep the viewer's eye searching everywhere for what is supposed to be in focus. I think this could have been a very powerful photo if you'd focused on the water, and left the foreground dramatically blurred.
This is a photo I did for a Harley-Davidson advertising campaign. It shows how you can have a drastic blur in most of the photo but still create a dramatic effect if you draw the viewer's eye to a specific point in the photo.
Good luck and keep it up! You obviously have an eye for color and locale!
