Drawn in 2006. This is the mouse that was on the cover of my "Marvelous Mice" portfolio. She isn't any particular character, just some random mouse gal!
IIRC, XianJaguar was at AnthroCon 2006. While she was coloring with her markers and colored pencils, I noticed she made her own color reference cards, and I thought that was a such a great idea! I went home and made my own color reference cards for my markers and my pencils.
It made color matching SO MUCH easier! Also, instead of using black to shade and white to highlight, I could instead use other colors, and I the look tends to be much softer than other art I've done.
