Yes, to all of the above! Maybe!
When I got home today, instead of sitting down and doing work, or indeed working on finishing off the drawing I have going, I doodled this. What is it? Well, I don't know really, but I rather like it. I'll think of a name later, but all I know for the moment is that it's a benevolent nature spirit of some kind. Am I sounding all Ghibli, yet? In any case, it would probably let you ride it if you could ever catch it sitting down (which it almost never does, since its joints don't work very well and it rarely gets tired). It likes butterflies, but birds get annoying and pull at its hair. The tiny little T-Rex arms are used mainly to push branches out of eye-level. It's very careful about where it puts its feet, and very slow-moving.
Completely drawn in pen! :D
P.S. I'm still not very good at scanning. :(
