This was a result of a rush job in OC when I had a thought about how to try colouring a piece. Tail growth and blue epidermis followed. This kind of fits in with the artist challenge thing too.

So, you're in the water one day and you think. "DUUUUDE, ring diving is awesome!" You hold your breath and under you go. About to grab the ring, you look back at a nagging feeling on your spine. Your favourite swim trunks are ripped open and destroyed by a ...tail? Arms flail at the water searching for dry land. No dice.
