Taranis - these are great. I know it's been mentioned on another thread but what software are you using to create these? I do bits and pieces of production work (logos and such, you can't really call it art) at work and use Illustrator, PSP, and Photoshop but would like to move beyond them.
Keep up the good work and keep posting them here. I think I'm going to use the one with the ships for my wallpaper at home!
