I really like how you portray Crona in this, I am not sure of Crona's gender so I am going to say "he". You do an excellent job portraying his masculinity and femininity even if both traits are vague. He appears surer and more free in his expression even though Medusa's snakes still to a certain extent control him. The color, composition, and anatomy are very good. And in general this piece sticks out among other fanart of Crona.
I Love it!
