This landscape is by Leo Eguiarte. I really like the colors in this, which are pretty much one of my favorites. And I also really like the texture in it. You can go to the artist's site and see more of his art here.

This digital speedart landscape/scenery is by jordangrimmer on deviantart. To me this is simply breath-taking, it looks so realistic. I just recently discovered this artist, and all of his artwork is stunning and absolutively beautiful. The details in the lights are amazing.
