There's a queer grin, Dutch touch about your painting that I like; but I've a notion that you're weak in drawing.

You foreshorten as though you never used the model, and you've caught Kami's pasty way of dealing with flesh in shadow.

Suppose you spend some of your time on line lone.

Line doesn't allow of shirking.
