Thanks. I agree about not knowing when to stop. I guess it's like a line from a movie, "Stand with your back to the mirror, turn and look at yourself really quickly and take off the first accessory you see," meaning less is more. Basically, I just copy what I like. :) It's a good way to learn new techniques at least, even if I never really use them.
Are you still having fun? That to me is the most important thing.
