Thanks for your comments. After re-calibrating my thinking and spending an afternoon attempting to reprint a couple of images I was not happy with, I've worked my way around to the view that better visualistion with camera in hand is really what I need to concentrate on. 4 hours effort brought me to the conclusion that I'm better off re-shooting both of them being mindful of what I learned printing. A nice little project before work one day this week!

Thanks,
