Either of the lower two, dude. They look a lot more "Natural". And watch out! Anne MaccAffrey sues fanart and fanfic writers at the drop of a hat, it is not a wise move for yourself or for Renderosity to even begin to try to mimic the Pernese dragons... she's even sued an artist who did a dragon that looked almost nothing like a Pern dragon... except the fact that it included multifaceted eyes, which she claims as her trademark for dragons...

Remember, kids! Napalm is Nature's Toothpaste!
