Abandoned art, watercolor squares

I started this project a while back with some Earth Day art, and it was supposed to be an "abandoned art" project where these pieces were left in public places for people to find. Somehow, it never came to fruition. The part that was missing seemed to be the most critical part of the project, a scannable code or URL on the back of the artwork to direct whoever found the piece back to a website to get information about the artist.
So here are the pieces that I had created to be abandoned. I'm kind of attached to them now and I don't think they deserve to be abandoned any more. All of these are done on 4x4" squares of watercolor paper. Great for Christmas gifts or maybe I should mount them into a grid in a collage frame to display them as one piece.

Just some thoughts about the art...
For some reason I was stuck on creating negative spaces...for the lettering, the flowers, the eye.
I love the eye, but realize the challenge in portraits is not in creating one eye, but in creating a second mirror image that matches! The "imagine" piece is a bit chaotic, but I suppose the universe as well as my imagination might seem like that.

Should I make one more to finish the 3 by 3 grid? What word would you use?
