you're not alone. I have not really achieved anything in the drawing arena since Christmas. I have sketches of a chibi comic (I was curious and wanted to investigate chibis) but it sits on my hard drive drawn, but not inked. I was trying to draw today, but my house is now clean, and have no energy to draw.

As to your HP magical creature, I'd vote for mermaid since I think that they have selkies.
