> I don't think those pictures are "drill, not scrimmage", in that they are themselves perfectly good works of art.

I agree that they're nice, but the author's ultimate desire was to make paintings, not ink drawings, and therein lies the distinction between drill and scrimmage (I think). For him, the ink drawings acted as drills in service of the desired ultimate product (the paintings).

For someone trying to get better at ink drawings, on the other hand, those ink drawings would count as scrimmage -- and I imagine the author would argue they should drill the sub-skills that make a great ink drawer (pen work, composition, perspective, shading, etc) separately from the ink drawings themselves.

The artifacts produced by those drills may be beautiful, but they're still "drills" because they represent only a subset of the skills the author was ultimately after.
