First thing I thought was pushing the digital zoom out a bit too far - hence the noise. Guess it was the tight cropping. I do find it interesting that out of 19 comments thus far, you only find one helpful?
ok, you got smacked. i'm quite sure this was not your intention, but, you've been given quite ample feedback as to what went wrong. now it's just a matter of putting this behind you, and putting yourself to work. you live in a beautiful area, you have a camera that's turned in some pretty high scoring images: all you need to do is keep at it! good luck with the next one!
I guess this is pushing the zoom to absolute max. I shows unfortunately. Its lost detail and focus, and to be honest is just plain bad. Meets the challenge though. - can't give you more than a 4, and thats because there are three of them.
