This is an adult dragon. It's a she, though there is no external gender distinction.
This is an example of some unusual colors that can be found on their coat, compared to the other one that has more natural-like colors.
This one is larger than the cub, about 3 meters long.
The head itself is larger than a human head, the paws are larger than human hands, although this individual has quite small and refined paws, they can be much rougher and stronger, depending on the individual.
It would be able to lift one person on its back while flying near to the ground. But that would never happen ever. Unless it has to lift a comrade, it won't lift anything that is not a dragon.
This type of conformation is called Northern Flying Type. They have other possible conformation, they don't all fly or look like fluffy snakes.
