answer to Dan Chusid: first of all, i need to say thanks to your comments on my gallery and photos. i am sure that your comments are loyal and constructive. Actually, i am doubtful about when i should use a fisheye lens. I found that some people like the effect of fisheye but some other people really reject it due to the exaggerating distortion. I confuse if i use fisheye or ultra wide lens during photographing large area. I would like to discuss this with you and listen to your advice. Thanks again. :)
If you can excuse my criticism, this is probably not the best choice of lens here. The scene is quite interesting and would have been perfect with a simple wide-angle view. Understandable if this was the only lens you had at the time and it still, like I said, is an interesting scene, and with character.
