Hello @tember. I like your collage theme. The man can escape his surroundings by the opening in the sky. All he has to do is imagine it. The zipper opening up to a new world is good addition to your theme. I like the color choices for the skull's head in the mountain. @eve66 tree with mysterious opening adds a nice touch of the unknown.
Thanks for including one of my fractal images in your theme. I appreciate it.
Good luck in the contest. Take care and have a good rest of your day.
