Many thanks for your complimentary comment Russ and Goran. I have to admit, I like it too

I added darks when I processed in Registax 6. Also did colour adjustment with the histogram in Registax, with a final "touch-up" in PS CS3.
I forgot to remove the artifacts bit at the edge and didn't notice the slight green cast until I'd uploaded the image. I'll have to have another little fiddle.
