Great work guys. I'm not sure how picky you want to be. As a biologist, I look for the way an animal (real or otherwise) works.Anatomical pictures are great references. Just remember, it's bones that we must build on (eg. watch the shape of the shoulder blades in your dragon). Also, the claws and horns need to be functional if possible. I like the backward pointing horns, but realistically they would offer the dragon little in the way of protection or weaponry.Also, be careful of the claws....if they're too big, the animal couldn't walk (look at felines...they have retractable claws). I hope this advice helps. I'm better as a biologist than a designer!! Keep up the good work.
