A quick update on the dragon model. I tried to incorporate some ideas I got from from feedback in my wip thread on blenderartists.org.
I corrected the size of the head and added some muscles at the base of the wings.
I have now to decide if I continue with the rigging of the dragon or if I stay with the modeling and start with creating Ara.
See here for a turntable video (without the table) of the current dragon model in a nice pose.
