I wanted to update Marina's design as well. I removed the orange from her color scheme and added her cutie mark colors to her jewelary.
Marina is one of Scratch Build's friends. Her interests include surfing, surfboard making and learning different hydrokineisis spells. She prefers to spend her time with Scratch Build and the two share an apartment with their other friend Folklore. She wakes up earlier than the other two so she can catch the early morning surf. If there aren't any waves she makes them herself.
