trace with bernie wrightson

Just trying to understand how these greats understand form by pure tracing over their work- this time I tried to trace over a Bernie Wrightson Solomon Grundy page. This was crazy on how detailed the work was- image it was 11X17 or larger- a lot of ink bottles were emptied on this piece.

I did this with Sketchbook pro 7- and was impressed with the response with the felt tip marker tool. this took me  a couple of hours to trace- image the time it took to ink this one with non digital tools- WOW- still impressed with this work...

My critique: I can tell I need to understand a curved stroke over a straight stroke and how those stroke define form- will keep working...
