Thanks for the clarification, Sammy.
I tried playing around with the original image for a while yesterday
but didn't like the way it was turning out. The image is pretty small.
I might try it again though.
You might be interested in checking out the Speed Challenges
if you haven't already. They're all about this same idea that you
are interested in.
Speed Challenges - PhotoCamel - Your Friendly Photo Community
I'm pretty new here but it seems that in the speed challenge one
person posts a picture (either their own or a stock photo

) and
then several people use it to make something new. Then the original
poster chooses which he/she liked best and then the person
that created the winning image gets to start the next challenge
with their own choice of image.
