You really need to stop spamming other artists for drawing dragons and gryphons 'incorrectly' because all you're succeeding at is annoying them and making yourself seem like a moron. Last I checked dragons are fantasy and mythical creatures which officially means they (or these versions) don't exist. Therefore they aren't subject to evolution or any other laws or forces in nature. If you don't like these versions then don't seek them out or heck, create your own. Spamming and trolling only earns you enemies and critics plus risking corrective action. There are millions of other pieces of artwork that would fit your preference. I for one don't like Spongebob, anime/magna, the Simpsons, Power Puff Girls, or Veggie Tales. So I don't seek them out because I don't care for them and it's not worth my time or attention. Centaurs, minotaurs, fauns, satyrs, perytons, merfolk, and nagas don't exist either nor they don't make evolutionary sense either. People with below average intelligence know that. (By the way, fish aren't tetrapods, but they are vertabrates.) So do yourself and the rest of the art community a favor and cease your spamming.
