Well, here's my first attempt at making a background. I wanted an Indianapolis skyline (since I live there) so I decided to make one. It's almost impossible to see SMS in Manila since it lays on top of lights in the picture.
Here's one that's a little better (you can see the text better) that I made for my wife. She wanted something with snow, so this is Central Park in winter.
BTW, I'll too will be taking requests if anyone wants anything special! I've found it's kinda fun to make these, so I'll share any I've made! Thanks to the OP for the details and links on how to make these!
