Looks better, but not by much.
There's several ways to shade, don't ever pillow shade!!!
Instead use differing, this is a technique where you use a bunch of shapes or whatever to transition from one colour to another and define a light source.
I made up a quick example in paint. Light casts from top left and creates a shadow on the sphere. I think use(attempt) dithering to smooth out the light transition. You'll find you can use any shapes to dither(circles, triangles, spirals).
Does this answer your question?(also, don't hate on my crappy dithering, I made the canvas too big and paint sucks)
