progressive with sketchbook pro 6

I am still trying to figure out how this software works.   I reviewed the youtube videos, and  figured out how to make a clean line.  One needs a good pencil brush and zooming up to 400%  and to practice sketching a clean line.  I am also seeing the blending tool sets. So I decided to do a work in progress...

This image is based off Will Eisner's character Antonio Tonatti from The Building graphic novella.  My first layer sketch was loosely made with a pencil tool.  The second clean up layer was made as stated earlier using a thinner pencil line and zooming up to 400%.  The third layer was made underneath the clean line using the paint brush tool at low opacity. Using several tones of a similar color, I can get a shadow and highlight look.  I then use blending tools also at low opacity and strength in order to blend colors and create some basic core shadows and cast shadows... My last layer goes on top of the line layer with a pencil tool at different colors to finish off the face  to look more rendered and remove the brown line in some areas or leave it as a different color when needed.... That's it! It was fun to try to do- I think the cartoony loose line look gives me more time for rendering to a more complete stage... I may think about this for comic production in the future- hmmm...
