It comes off more plain than it does simple. If you're trying for a more minimalistic approach, I'd recommend mixing up your colors. Or using some form of effect or idea that has a little more impact, especially if you're only going to be using it so sparingly. Not a big fan of the text, either. I'd rotate it to be at the same angle as the horizon, and maybe play with some other typefaces.

Pretty decent overall, good work on trying an uncommon style.
