Okay, that's weird...I thought I put the photo here but it ended up showing up down below on the moved thread!
Let's try this again...
I added an omni flashlight around the stamen area of your image to help bring the light from the base of the flower up and out into the top area using the Render/Lighting Effects in PS. It's just a thought...
Hi Randy. Love the subtle details you achieved in the whites. Julie's repost is an interesting alternative - not sure which I prefer at this point. Well done.
Randy, check out also Nik Color Effex Complete, I think you can download a trial version. They have reflector effects, yes, silver, gold and soft gold, and you can play with the intensity and direction of the light!!!!
