Wow, hope you were careful with those raggedy edges...this is really cool looking, and yes a Diet Coke can would be very shiny, to make use of reflective light.
I have been busy lately, so I've not been commenting that much...but I realized that you haven't been on for a few days. Thinking about you...and missing your pics.
Re: A tree hugger, that's funny! ;)
Awesome photo, Naomi! I like the way it's composed
Love this shot!
