I didn't make it!
I was touching up a couple of pictures I'd taken before to try to make them more suitable for being a good background. Anyways, here is what I've come up with. For each set the first picture is the original. This is the first time I've really done any kind of touching up for photos, so I wouldn't mind some pointers.
The first 2 were scaled up from 1200x900 to 1400x1050.
This next one is 3280 x 2260. Open at your own risk. The second in the set is only 1400x 1050 though.
The first one I was trying to just make the picture look a bit better after being scaled up, but I don't think I did too well. The second two are more trying to make the pictures look awesome, not just touching up.
