I know there's been some comments about the cloud and Im' not sure if that's what I'm seeing but there is something strange on the right side, just above the little island. It looks like something was cut from the image or cut from another image and added to it. I wish I had a way to point it out but I don't!
Other than that one little thing in there, the image overall is really great. Far better than my first attempt! Keep up the great work!
