I love Aerodactyl. This is a great piece and like how you added spikes and more teeth. However I am surprised you did not go for a more brutal Aerodactyl. The Leaf Green Pokedex entry states, "A ferocious, prehistoric Pokémon that goes for the enemy's throat with its serrated, sawlike fangs." So I would have expected Aerodactyl tearing another Pokemon to shreds, is all. Keep in mind I still really like this illustration and I added it to my favorites.
