I've put a little ink on the pencil drawing here-- actually I'm working on a computer print of the pencil sketch.

I haven't erased or "cleaned up" the pencil so you can see where I've been. If this were a more polished drawing, I would clean it up.

Once I get a pencil sketch going from the photo, I usually set the reference aside and do all the inking out of my head-- a little to-and-fro with my sketch.

Things like: the fact that elbows have little knobs of bone under the skin-- the triceps "grips" the upper arm from the back like a pair of pincers-- don't forget the ribcage-- toes and fingers are not lined up symmetrically like little soldiers-- there are conspicuous tendons in the top of the foot-- a little voice inside my head says all that . . .those things are part of inking without being confused by the reference-- photos are great information but they contain a great deal of distortion.

And "copying exactly" from them is asking for a world of grief.

I've tried to suggest a context for the figure to occupy-- with some pen and more thin brush strokes. The figure itself is all in brush-- Dr. Martin's Bombay India ink on Ingres paper-- I like the grain for brushwork.

This is not a "finished" drawing necessarily.

I just drew this figure from Scalera's photo for this demonstration. But if the figure were in a comic book or graphic novel panel, I'd evaluate it further and re-draw-- white-out--or simply "computer erase" part of it , if I thought it was getting congested.
