Download for 1024x768, 1280x1024, 1600x1200, (with and without shading) and reference.
Kagura taken from the Azumanga Daioh manga. I'm not totally sure if the shading is even necessary/appropriate where I put it. There were lines all over the place on the original image and I wasn't sure which ones I should emphasize in the trace so I just picked the darkest areas. Not sure if it looks better with or without them though. Oh well.
