100days, day 6

I'm still annoyed after yesterday's lesson. Trying to persevere though, and keeping up the 100 days by reading. This chapter is getting into light, with some science involved, and lots more talking about shades and colours. Then, finally, a multiple page example getting into moving from cross hatching to shading; involving many different pencil levels. I thought we weren't getting into that; but looks like we are.

Continuing to ponder rolling back to the start for some reviewing. Or maybe I just want some reassurance by doing some easier exercises. Hopefully with more skill this time.
