What you're able to see in photography is the real key and you have it in spades Marianne. All the expensive gear, materials and development minutea in the world isn't going to get these results without that vision. Way to go!
bill, i guess its a good thing i have a bit of "vision" as you called it cuz lord knows i have none of the other things you mentioned! for me it is, and always has been kind of a crap shoot and i am flying by the seat of my pants most of the time, but i do know the look i like and once in awhile, everything clicks...
