I like most of the shots, but two things strike me right away:
One, go back and fix the simple things, such as tilted horizons - it's very obvious and screams SNAPSHOT when a nice image comes up and the horizon is a few deg off canter.
Two, they look great with the super saturation - on the screen. Would make very nice backgrounds, screensavers, etc. But as I'm sure you know, prints will be a far cry. If you are going for an unrealistic look, then great job, they do look very nice. But if you intend on actually printing them, I would make your images with that intent, and at least tone it down nearer the output gamma. If anything, it'll save disappointment when you compare the monitor images and prints.
