Thanks all for the comments. It's great to have other people enjoy your work. Much of what I've learned has come directly from the wisdom others here have shared.
Alpha Chicken: The only image that's had any serious PP work is the 2nd one. I used the Orton effect on that one (duplicate layer, gaussian blur, multiply blending mode). I can't recall if I did anything to the other two. Maybe an unsharp mask or slight contrast adjustment. I'm pretty sure those two are as is though. And as for the quote, yup, Ansel Adams had a lot of great quotes, but that particular one has to be my favorite. There's just too much variety in life to try and place rules on how something should be shot... Cheers!
