The final version of my previous drawing.
Okay, now some explanations.
Tosca is a well-known character from a very dramatic opera, "Tosca" ( http://en.wikipedia.org/wiki/Tosca ). Her dress is inspired by the one I saw in some pictures.
This will be the cover for something I've been having in my mind for quite some months; since it's a cetacean-based project, and tied to my website's name ("The Reef Opera"), I chose a species known for its chants and expressive muzzle acting in a dramatic role.
And I've tried to put the blowhole in a more natural position than what's usual for me.

EDIT: I've fixed her arms.
