Press "space" to see my reference image. GD stands for (is an acryonym for) Graphic Design, in case you didn't know ;) @oriquack for the "zoom-in" mouse code!
I did a blockshade of @Hanzhe's bunny from his Magic art dump! You can see I didn't do some of the lineing, but other than that I think it's pretty good :) Use your mouse to zoom in!
