This is an original concept i made for a short film. Here i'm working on getting the concept to better work for modeling.
I'm primarily using Photoshop's lasso tool with move and brush to try to better adjust the line drawing. I'm also using the ruler tool and guides to help line things up
some of the tasks involved in this (30-45minute project)
--base of feet lining up across 3/4, side, front
--top of head lining up
---waist lining up
---chest lining up
---under jaw lining up
---merging line drawings into one layer
---begin to block in hints at planes for 3D using grey scale tone
As can see the perpective nose not quite lined up would still need some tweaking.
Reason this is helpful is during modeling, example ZBrush can match proportions more closely to the design.

(Tip: ZBrush can be a great tool to get multiple views of a concept 3D design quickly. The zapplink character sheet can create views automatically and quickly. These can then be used as a starting point for more design development)
