I thought of drawing a "what if" scene where Ozy and Millie had their personalities swapped. It's not done yet, but I'm pretty pleased with the half that I've finished so far, so I'm posting it now. It still needs Ozy to complete the picture, though.

I used a mechanical pencil for the linework, then an HB pencil (the non-mechanical kind) to do the shading. Scanned in 1200dpi, cropped, and resized. I'll clean up the stray lines in Photoshop when the whole thing's done.
