So is it Pegasi?

Lookee here, several sketches this week. I know, I'm spoiling you. But I do have a burning question: is the plural of pegasus actually pegasi? Or is it pegasuses? Please help me out if you have an educated answer for me.

Besides the pegasus or three, I did some mermaid sketching this week. Lots of fun playing with the flow-y hair and curving shapes. I guess this gal is a queen of some sort? Let me know if anyone has a story idea.

Lastly, I've got a tree drawing. Tree drawings are just something fun that I always enjoy doing.

I suppose everybody is gearing up for Halloween? I'll actually be out of town for the weekend. So you may or may not get a blog post out of me. It will have to be either early or late. We'll see...
