Ok, here's the most recent update:
I added two more Omeisaurus, one of which is rearing to eat higher branches.
I think I got the neck a bit TOO thin on that one, but I'll iron it out on the next update.
Also the dynamics of this graceful creature as it walked must have been truly marvelous, considering that most sauropods are usually depicted (incorrectly) as super-obese, ponderous hulks just barely plodding along at snail pace. This guy was the sports car model, while titanosaurs were the bulky "SUVs" of sauropod-dom. Also if you look closely notice the big thumb claws. There were a lot of sauropods that had them, but Omeisaurus and its kin had possibly the most oversized ones ever known. I can only guess that this was a very useful active defense for a creature that was not quite massive enough to rely on size alone as a deterrent for the packs of big predators of the day.
Also I added more trees and more background to the Shunosaurus area, with one on the hills just behind. It's shaping up very well so far, IMO. The most tedious part will be the trees.
