Margin Drawings (My Muse on Niven)

I'm putting this in Miscellaneous Characters rather than under Books by Title because these aren't strictly attempts at illustrating a book I've been reading. The woman and man are loose ideas of what characters might look like, the furry alien thing is just an offshoot of my speculation inspired by character speculation, and of course there are objects here that don't properly have to do with anybody, and might or might not look anything like their inspiration.

Anyhow. The short version is that this is my muse on Niven, as I've recently begun reading Larry Niven & Jerry Pournelle's "The Mote in God's Eye."

(I know that Submission Quality Guidelines part c) says "no lined paper," but then it clarifies "where you have made no efforts to erase or otherwise reduce the lines from the image," and I did some erasing and reducing where the lines weren't covered by ink, so... still counts?)
