Moon character designs

These are my character designs for the imaginary animated film we're working on in storytelling class. (We're doing all the planning up to script and storyboarding, just not any actual animation.) I love my story idea a lot. BASICALLY Ruth and Frank are a young married couple and they live in a bubble house on the Moon and one day Ruth looks outside and finds a little lost moon child wandering around. So she has to help her find her way home!
