@suzanne234 Thanks Suzanne - I appreciate your comments. It's actually a lot brighter than real life - I dithered about whether to use this one or a much more subdued one - but, what the heck, it's an editing challenge..... :)
@jgpittenger Thanks Jane - it was a bit of an experiment - still needs work I fear. But I learnt a fair bit about the amount of transparency to use. Thanks for having a look. Cheers Rob
