The number/arrows above the left-hand door don’t look right – I’m not sure whether to re-do them, or to try something else; but I’m going to paint the Librarian first. A change is usually as good as a rest; and whenever I’m unsure about something, I find that putting it aside for a while enables you to return to it with a bit more objectivity, and a clearer view. I think the scene maybe needs more slime, as well. But we’ll see.
