Thanks for feedback, Derek. With regard to the colour, I wish I could remember how I got to this point with this image (and indeed many others). The advantage of playing around with software in a relatively disorganised fashion is that you can end up with results that are spontaneous and unfettered; the disadvantage is that if you want to repeat the process, or share it with others, is that it can be well-nigh impossible. With this photo the colour results from playing with the lighting adjustment tool in ACDSee Pro 5 (a graphic equalizer approach) and then introducing some greyness and texture with Filter Forge Photo Effects (part of their free set) using the "grunge" setting and playing with the default settings.
