Another one of my old snail and mushroom shots! The composition ins't great, but I know that lots of deviants liked these photos. I remember people commenting that the photos reminded them of Alice in Wonderland, so I named this one for them! The purple mushroom is purple in real life! They're called amethyst deceivers.
I don't think there's anything wrong with your composition, considering the fact that nature doesn't always accommodate our ideas of placement. I love the colors and just catching those two mushrooms side by side is a great find!
