I'm sorry to say, in my haste to beat the deadline I failed to update the previous version and quickly added this as a new one, so I lost your comments. Sorry about that.
This is a different image to that originally posted. I'd always preferred this version of the composition but had real trouble getting the colours where I wanted them. Resorted to Aperture + PS in the end to drag the colours from where they were hiding deep in the raw file! -Najinsky
