The raptor species seem promising; I'll look into them when they're posted.
Unless Pyrod has that taken care of, can you also make one based on the Pokemon Aaken/Archen and Archeos/Archeops?
[link] [link] These two Pokemon are based on Archaeopteryx, so those are the first things to look into. However, since Archeops also has elements from the JP raptors, it would be a good idea to take those into consideration as well.
As for the art trade, that's great! I'll remember to get started on my half really soon!
