Thanks everyone
Lynnie, you could download Free 30 days trials of Adobe Photoshop then of Macromedia Fireworks (basically, same thing) or get Paint.net. It's a free program that, obviously isn't as good as Photoshop, but close to it, while still being free.
JekyllJuice, actually it's my wallpaper right now

. That's why I made it so big
And here's another picture that I just completed, which I'm sure Cass will be very fond of
For any other pics I might do, I'll probably just post them here instead of creating a new thread.
