An experiment with outline...

Two of my dragon characters I just realized how similar they are. Both of them, I designed to be unanimatably complicated as a challenge to myself XD

Slan, the above dragon, was a Babylonian temple prostitute in her human life. After a couple of random curses on her corpse, now she's an immortal weather goddess who fashions castles out of clouds; she's very pensive and is enraptured by the strange behavior of the creatures she's glad to no longer be one of... Sort of a quetzalcoatl design, I don't remember how I came up with her.

Mencia, the bottom dragon, is sort of her polar opposite. A mediaeval Cantabrian Cuelebre, she had body image issues as a teenager born to nobility, taught from birth to believe her worth lay in marriage, and yet was cursed into this form by a jealous Xana fairy (they think they're the most beautiful creatures in the world, and curse vain humans).
Wracked with self-pity (part of the curse is that a Cuelebre cannot be killed by fewer than three people at once, so she can't even kill herself, not that she's not tried), she sits in her cave, her sole mission to guard the much older and fiercer dragon at the bottom of the cave, her sole moments of light her dragonkitty and rock-sculpting and the occasional visits from her twin sister Agueda. And her world turns upside down when an impetuous knight leaves his squire as ransom with her... longer project.

They're both winged serpents with ear wings, interesting to draw - the former because of how loose and loopy her wings are, the latter because her body is twisted (her arms are now those teeny wings on her neck and her legs are her flying wings, she complains that her lizardlike limbs are like being strapped onto a horse) and wracked with every mental problem under the sun.

Either way, fun characters, fun sketch!
