I was hesitant about the colour scheme this character had in his description, with the colour of the head and wings being so sharply divided I didn't know if it would look as good in execution as the commissioner would like.  

To my surprise, however, it worked out just fine.  I'm still very pleased with this pic, with how nicely the shading on the head and wings came out, giving it a perceivable texture, and the shading on the body, with how the shaded areas are nicely dark and contrasted, but softly so.

Another dark background, with just a touch of pencils over the markers here and there where needed, with layers of cool grays added over normally added base colours.
