Carrier Pigeon Unicorn Illustration

I have been experimenting with mixing various techniques to create tone for MakerBot Unicorn pen plotting, taking advantage of schmarty's "Unicorn G-Code Extension for Inkscape?" (http://www.thingiverse.com/thing:5986) and dnewman's "Inkscape hatch fill extension." This pigeon will be part of a bookart project I'm working on -- and I will continue to experiment with forms of hatching and crosshatching to give this little drawing tone and dynamics.
