Writers, Do You Also Do Art?

I’m curious about this.  If you’re a writer, do you also like to do your own art?  For example, character art, scenery, buildings, and even cover art.

I consider myself to be pretty decent at drawing, so I can do a lot of my own conceptual art, though I’m awful at doing faces.  I’m much better at landscapes, buildings, and still life.  I can also draw animals and plants fairly well.  But I always have trouble with people.  I’m good with pencils, but terrible with paint.  I also haven’t had much experience with digital art, as I prefer good old paper and pencil.  I will be doing a lot of art for my books, except for people.

If you can do art, what do you like to draw?
