The dog's face is framed by the door to the coop. Within that, the carefully-placed highlight also hugs the face. Fagan's framed by the coop's wall. Nice details like the tree and the sack also embellish but frame the interaction between these two.
The characters are making eye contact. The dog's line of action is straighter than Fagan's, and it's related to it, but they aren't parallel. They almost form a "D".
The boards on the left, back side of the coop are totally mismatched from the closer side. It breaks the shape down into something more organic (much like the shingles on the well from a few posts ago). I had to resist the temptation to line them up. I think it's funny this way-- this coop was built by hand. I should bear this in mind when I do my own backgrounds. Man-made stuff can be misaligned and asymmetrical (organic!) just like natural stuff. Especially if it's made of wood, and probably by somebody's grandpa.
The board that is atop the coop's door that stretches all the way across was messed up in my final lines. I made it way too small on the far side, so it sort of clips awkwardly. I need to be more careful about preserving shapes like that.
I accidentally made Fagan squeeze himself too much-- to the point where I skinnied up his abdomen! ;)
I think the hardest part about studying Eisenberg is his treatment of eyes. They're so tiny that they're very easy to mess up-- even a few specks of poorly-considered graphite change the directionality.
