Andrew Loomis "Successful Drawing": "No drawing is real drawing unless it is related to an eye level or horizon."
Does this means even a hand study should be related to a physically drawn horizon? But then even if your just doing a study of form,
without the horizon or eye line, it will in some way be inaccurate no matter how accurate it actually looks?
From what I've seen in most figure studies in peoples sketchbook, they keep the eye line in mind - but there's almost never a physical horizon line.
I don't know if this seems like nit-picking, but I'm really trying to start back at the fundamentals and give drawing a proper approach.
