As ever, interesting opinions. Yes, Eric, this was taken on one of the very few frosty days we had in Manchester this year. It's a focus blend of half a dozen images, taken with some difficulty because the 24-105 was suffering badly from zoom creep, looking straight down as it was. Slobodan, I saw this as a pseudo-abstract, deliberately without a particular focal point, and I liked the contrast between the frost and a warm tone.
Thanks, all.
