This one is unique in that I decided to redesign the character while making this icon so it's a look into what they may look like in the future.

A lot of my old humanoid designs had multicolored hair which sometimes look ok or just clashed. For some of them I kept their strangely colored hair while for others it got updated, Marsh is one of those. She gets to have multiple colors but now they sort of look good together and I felt like she was somewhat similar to another design I had.
