I was thinking about which fish to base her tail on, when it hit me, that you don't often see a mermaid with an eel's tail. Few moments later I found some pictures of a couple of eels - and this girl found her way from my pencil to the paper
Please ignore the derp dolphin silhouettes... I was simple annoyed by the plain background, but could not convince myself to actually put in the effort to draw some proper dolphins. Who knows, perhaps some day, I will come back to pay them justice?
