Fanatic on Artwork

Well, today my computer must seriously hate me. I made three more Terraspace images, one or two I may do more with, but besides that the quality was set to maximum for the images, so the render process with the shaders, shadows, textures, and detail took about two and a half hours, and if it didn't take a long time, I changed the settings and rerendered it. I'm a fanatic about the quality of them.

I love my computer though -
2x 3.2 GHz Pentium 4 Processors
256 mb Radeon X800 Pro Graphics
1024 RAM

and then some... Definately does a great job, but I feel as if I require... more...
