Is it normal to run into anatomy problems with bodies and faces if you rough them out with the smaller "finalized px" size rather than some bigger rough brush? I usually have this problem with faces and bodies at least half the time, I would try to draw a head at an angle with the loomis method and fail most of the time, then one time I made a bigger soft "block in" brush, then just made vague rough shapes and outlines, then drew over with the smaller brush...and had success.

I think some traditional artists do this? Draw rough shapes with a bigger/dull pencil, then tighten it up/finalize with a normal sharp pencil. I know some also make thumbnails and upsize it on computer and print to lightbox over.....so I guess people that can draw with thin lines from the start just have more experience then?
