Awesome. Don't you think the mouth looks a little one-dimensional with only one row of teeth showing. Given the angle of the head one would see the other row of teeth in the lower jaw. Just my 2 Cents..
It's amazing what you did with just one source.
Nice work, I agree with both Tarkus and NewsMaster, great work from the one source, and I do agree about the teeth
You be the dragon king, three of top 10 very good.
