For the body of the beast I used a heavier guage wire and twisted it like I did the wings. I then just bent the wire to what I thought was close to the thumbnail sketch and started adding plasticine for the body shape. I then bent the wings to shape and stuck them to where they should go.
I cut some black material and glued it to the wire...not an easy task! After that I brushed on some retouch varnish to the material to stiffen it up some so it could hold its shape.
