It's MerMay, so naturally I had to draw Erik and Christine as mermaids. Erik would definitely be the deep-sea, spiny type...Christine's probably more of a freshwater siren.
Also, I can't stop thinking about how Erik would breathe underwater without a nose? Gills, conceivably, but, you know...one would think the water would clog up that nasal cavity and make things pretty difficult.
