Please forgive me for working with your shot, but I do this only as an example of what I think might really push this marvellously broody image, even further - I also realise I will probably reap the wrath of the anti croppers by suggesting this, but hey ho, my skin is becoming armour plated these days. Also if you do not like what I have done here, then please say so and I will immediately remove this reply and this cropped version from the thread - the temp version on my PC, has already been deleted as you read this BTW.
So getting down to what I think, the shot is excellent, and for me invokes a sort of nervous feeling of a totally bleak (weather wise), wind blown isolation. All the elements (excuse the pun) are there already, but to focus the viewers attention even more tightly onto those feelings, I think by cropping it down to what is the absolute barest essentials of the empty and bleak aspect of the shot, really helps to intensify that feeling into the viewer.
So as I say, this is only a suggestion and I am sure some may not agree, but for me, the cropped version certainly gives me a feeling of complete and shivering isolation.
So I don't know if I am allowed to give you a Bravo for my cropped version of your image, but if I can I will - Bravo!
