Looks great, Fuji. One thing that's bugging me though is the rib effect on the wings. It just looks like series of fuzzy gray stripes. Here's a technique from Simmer's Paint Shop that might help you improve the effect: http://www.simmerspaintshop.com/forums/f34-general-tutorials/fabric-surfaces-hard-way-718/?garpg=4 (start with page 4, the first 3 pages detail rib placement - which you've already done.)
Very nice
Fugi outstanding!
