Painting with or without microbes

I believed too much that my microbe was going to make some fantastic colors for my art, but my faith was misplaced and only one of my works came out okay. The whole piece turned out pretty well and the colors are as good as I can ask for from microbes, so I’m happy with it. The EMB plate made my tree base turn slightly purple and the branches a light gray. I chose the colors based on the way a tree looks covered in snow during winter. The plate did not have much room for me to work with, so a tree was the best I could fit in without ruining the work, otherwise I might have made a different picture.
