Farmland at Dawn

This is looking east from the mouth of Cedar Canyon. The sun was just coming up and the greens were very vivid. I was also attracted by the layers and haze. I am also including a second image. I had included a tree as a foreground object and then couldn't decided whether it looked better with or without the tree there. The first on I cloned the tree out. I would appreciate your input and critiques. Thanks
