One thing you should learn is that sending a psd file doesn't help you learn new techiques. It's just a bunch of little thumbnails, and the image is directly editable. Someone a while back wanted a psd of one of my wallpapers, and well, he didn't get much out of it. But if you want to see one, I'll try to make something tomorrow that you can view the psd of that's not a billion layers.

If you want the psd file to THIS image, you'll be slightly confused. There's around 30 layers, and most of them are textures.

I'll AIM you tomorrow about the details. Gotta do some homework in a few minutes.
