Progress / Mouth fix

Mouth fix

When a dragon roars you should be able to see into its open mouth from the side. On the first builds a wide wall of cheek skin hid most of it. The fix shrinks that wall so the tongue, the teeth and the inside of the mouth show, on every dragon.

Every picture is taken at the widest point of the Roar. The first picture in each row is the published model before the fix; the others are the second test round of the fix. The small inset marked "production" in the last two pictures is the same view before the fix. Eight dragons went live with the mouth shown here: seven passed that round's review, and Terra went live with it too, with two small points accepted as they are. Heatfang, Toxibloom and Glarebyte needed one more round. All eleven went live with the fix on 29 September.
