Good start.... keep up your good work !!!!!!!!!!!!!
I like the desert render the best. It only needs a power fractal added to it for more coloring.
This time foggy style ^^ (http://img291.imageshack.us/img291/1276/mgla.png) (http://img291.imageshack.us/i/mgla.png/)

What settings did you use on the last image? Try increasing the atmosphere settings to 48 or 64 samples in the quality tab. I would also increase the GI Enviro surface setting to 1.5. In the render tab change the GI sliders to 1, top and 3, bottom and check the GI checkbox. It's a nice image, but appears too dark.
