First off, thank you SO much for taking the time to critique!! I really appreciate that! (:

Thanks for bringing the depth perception issue to my attention--I need a lot more work with that. The clouds are pretty flat, too. I think some skyscape practice is in order.

That would be a lot of birds! If you're curious on their diet, Asera is a mostly insect-based world, most of which are on a slightly larger scale than earth insects. Baleen sky whales feed primarily on insect swarms. Prehistoric sky whales like these, however, are the only sky whales which feed primarily on other sky whales (or people and livestock, on the rare occasion).
