My First Photos with my new 20D - Southern Utah

[LRDesign]

I am new to photography and a new 20D owner.
Here are a few photos that I took this past week in Southern Utah. At this point I have no real clue what I am doing, so I am learning the camera and the art of photography at the same time. Let me know what you think.
These photos were taken out of the window of a small plane over Bryce Canyon, shooting thru plexiglass is quite a pain.

Thanks for looking.

Here are a couple more. These were taken in Zion National Park, stopped to take a few pictures and climbed down the canyon into a riverbed and thought that the dead tree stump was pretty cool.
