Nice idea on those Zapdos wings!

I noticed the Lugia looked like a pterosaur hybrid (rhamphorhynchoid tail, crest of a Pteranodon species and what looks similar to Aerodactyl wings sans claws) midway through Darwinian evolution into a species of bird. It's a possibility in the Pokémon version of the Mesozoic Era although the Archen evolution line appears to be a more plausible missing link.

I like how you've depicted the legendary birds as they would have looked in the real world.
