Wow man this is cool
The arms the faces and the eyes! Its truly a fantastic style! Going straight to my favourites!
He got an A, that's all that matters.
I'm going to review this as a whole, and not as a "copy the style" drawing.
You're right about one thing: even though the drawing is pretty expressive, it just doesn't look whacky enough. Overall it's okay, and I noticed how you put that background highlight on Gregory so you feel sorry for him. I give the score of 8/10.
