I'm finding that I need to approach the way I choose lunar targets a little differently. Most of the time I pick my targets and stick to them, but calculating the position of the lunar terminator isn't always a guarantee that a target close to it can be seen (or seen well). At this point, I think I'm going to proceed with picking two or three targets for each lunar session, but commit to sketching the one which is best seen (or most interesting).
This was a pretty neat observation. The terminator was slicing right through Mare Humorum, and I wanted to represent that as best as I could in the drawing. The Gassendi crater is the largest crater represented (to the north).
For the bumpy terrain to to the northern and eastern side of the mare, I attempted a new technique. I took a brush that I was not using and trimmed the bristles down to be short and stiff. Then when applying the white acrylic I would tap it on the page to produce more texture. The effect turned out quite well, especially after it's applied to a "lighter" region where the acrylic has already built up layers through brush strokes; this gives a better impression of varied terrain levels.
I have also been making better use of a kneaded eraser (I've never used one before). It's been pretty handy for cutting deep shadows or to reduce a highlight without smudging it.
A tiny sliver of light was showing near the middle of the mare on the shadow side of the terminator. I'm not seeing any tall terrain there, so I'm guessing it was the edge of a small crater.
The Vitello crater is the one with a central peak represented to the south.
