Heh, yeah it's okay...no offense taken. I do as well, there is something about charcoal that makes the rubbings look surreal, dark (obviously), and obscure. Marker definitely fails to recapture it; but we had to draw them so we can copy/Xerox them correctly.
Definite flaws I can see would be obvious disproportion (some of the squares of bond paper were wider/taller than normal printer paper), bad drawing on "Insanity" (by that time I had decided to not care so much about the actual drawings but instead to pinpoint the "values," as it were...), and lack of light on some parts (whenever I went back in to see what I was missing, I would randomly convince myself that parts with necessary contrast were "too light" and needed to be slightly shaded...just me being finnicky I suppose).
