For those of you in the "but this isn't a photograph!" camp, my apologies, but I felt like posting something a bit different today.
This one started life as a fireworks shot. Subsequent amendments include motion blurring the original and producing four different colour schemes on a seasonal theme: spring, summer, autumn and winter.
As always, I'd be interested to hear your thoughts, not least because it's rare for me to post something quite this abstract.
