My [rubbish] shading drawing thing >,<
Comments welcome, but don't be too harsh, please?

Already pretty good. I especially like the coal-effect you created on the shadow of the big sphere(the shadow on the floor ) . The small one on the right looks good as well.
You know how to place a shadow correctly, the only thing that I'd recommend to you is not to use the blend or the smudge tool for shading. Usually, the airbrush tool set at a low opacity creates a better effect (especially in black and white drawings).
But that's of course just some technical trick concerning the Oekaki. ^^
