Hey, here is my interpretation of my friend Bill in his Arkady personality. He normally reminds me of being a gruff skinny Irish satyr xD

As you can tell, I replaced the Line Art of him with the final Color version. Some of the shading bugs me….
But as something special, let me give you a peek of the image as it goes through beginning to end!

This is the original, drawn of paper with pencil and then uploaded to my computer via tablet (I do not have a working scanner):
bill_orig

Then, I do the line art in Illustrator:
billy_line

Next, I do some base colors in Photoshop:
bill-color

We add some highlights in a separate layer:
bill_highl

And finally, we add shadows in a different layer:
bill_shadow

Make all layers visible and its done!
