I prefer cityscapes to landscapes because I like the energy of the city and hoped I had captured that in my street scene.
Cityscapes are great subjects because there are so many of them, and so close at hand for most people. Keep looking around for different views, and you'll find some good ones. Here's one I took with my first digital camera in 1998 - it's Baxter or Fargo st. (don't remember which) in L.A., and a 25 percent grade hill. I would like to retake this sometime with something that shows the depth better. That's the main thing, anyway - try to do something different.
