You know, when I'm feeling down, Queen and The Beatles are pretty good therapy :)
I also had good fun drawing Melvin, because well, he's a minotaur in a school uniform. Also, researching images of harpies was pretty scary. Apparently they are relating in some myths to Sirens, those creatures that lure sailors to their deaths with the beauty of their singing. If that's so, then we all know who got the good singing genes in that family.
Also, in terms of sound, it might help if you run your fingernails down a blackboard while reading the dialogue for Ms. Harpy.
