Made with: Photoshop.
Fandoms: 4 Veronica Mars, 2 Firefly, 1 Lassie, 3 volcanoes.
Artist's rules: Comment/credit/no hotlinking.
A few of these have been sitting on my computer for a while, so I tweaked them, added some more and here they are. I'm not really thrilled with any of them, I guess.
Sources: VM caps from Veronica Mars Screencaps.
Firefly caps from Can't Take the Sky.
Volcano image from here.
I can't find the source for the Lassie image. Just image-google "Lassie" and it's sure to come up.
