The person is a little too central for me, if you can set your crop tool to 610 pixels wide and 505 pixels in height and start the crop top left i feel gives a better composition getting rid of some of the space on the right, i also feel the image lacks contrast and would benefit from a levels adjustment, even the auto levels button if you have Photoshop gives a more pleasing image. the file size is a little small as well, this leads to a degradation of the image, try posting at round about 100kb if possible. You may have some dust problems as well. Sorry if you think i'm getting at you a little but i only comment on what i see and hopefully my comments are of some help.
This has so much potential as a dramatic image but the colours are dull and the composition too central. The woman is the main source of interest for me, but I can't see her. Cropping is subjective but I would reduce the amount of sky, get rid of that distracting bottom corner, and have her placed more to the right. Is it a scanned image? It's so well seen and a great subject, but it hasn't quite made it. Janhttp://janpudney.net/ http://jaypea.redbubble.com/
