eikin: no worries
globalshooer: thank you for the comments, I shall work on the S curve in future more.
tucker: I'm not sure about the issue of details lacking but sometimes i remove details to shift the focus elsewhere within the picture frame
denniskee: thank you for the valuable information, I now understand ND filters much better!
shojibake: it is interesting for you to include scale in the discussion of this photo, I have for some time felt that scale plays a large factor in the success of a photo. finally someone to identify with!
nemesis32: I am as puzzled as you are, on my monitor the differences are not so pronounced, but after viewing it on a CRT monitor, the difference in lighting is indeed huge! I am puzzled, really puzzled!
hazmee: when I first shot this, I did not have any intention of making it a gloomy or negative one. however it seems the photo has given such a feeling to many people, perhaps a mistake on my portion. what I wanted to create was a sense of movement and abstractness and solemness.
thank you all for your comments! I am touched by the number of replies from my first posting, it encourages me and I will definetly continue to post more here! any more comments on how to improve are more than welcome.
