Some great photos here, your a great photographer, thanks for your comment on my photo of Canary Wharf on flickr. I've only got into HDR in the last few months and I'm really still only experimenting with it, although getting some good results, please have a look at my zenfolio website, I've not had any visitors yet! :(
