I'm feeling back on track, now. I finished all of the stems and I'm done with the brownish green used for the hills and main stem. I didn't much like the block shading on the main stem. Having done it now, I know how I'd improve in doing it again, but it won't be on my favorite's list. I think to be most effective it needs to be very, very regular and square and I'm not a regular and square kind of person.
