Drawing a Dragon In Flight
Step 1 - Set up the Body and the Winglines
I usually start a dragon in flight by setting up the length of the body, and the length of the wing's leading edge. In my mind, the body (with tail) is nearly the same length as the wings, but the wings are slightly longer. The membrane between the wing's thumbclaw and the shoulder is an arc that's not as long as the leading edge of the wing itself and the forward fingerbone, but you can play around with this. Bat wings are excellent models.
