On my character, it's easy to show what wings I like. I like it when the webbing ends at the base of the tail or even goes all the way to part of the tail. I like big wings and long tails, so that it looks realistic and when you can think - yes, this creature could fly.

But in this case it is the customer's design and my job is only to draw according to the description. And to translate someone's idea into reality.
But really, what difference does it make? We all have different tastes, there are wingless dragons that can fly. And it's our imagination, we can embody whatever we want ^.=.^
