I'm going to attempt to show what the different dragon species look like in my simpler drawing style so I can at least have something to look at and edit as needed.
Here is a young, gender nonconforming reefwalker going for a swim. You can identify his gender nonconformity by his shell necklace, usually seen on betrothed female reefwalkers. A rare occurrence, but it's generally accepted within this society.
Reefwalkers are flightless, their "wings" having evolved to help them swim in choppy water. They are not as equipped for deep dives as their polar cousins, hence being named for walking among the coral reefs. Their many whiskers help them forage for food underwater.
