You're right, but I was just experimenting and I drew it withought thinking about the fact that it's virtually impossible to hold the sax like that. Yes, it's a speedpaint. Everything from 1 minute to 10 hours is considered a speedpaint.
Wow, love it! Kind of reminds me of the comic "Blacksad", maybe you've heard of it? (it's a spanish-french comic) It's a detective story set in 1940~ America, but the thing is that every character has an animal's face (cat, dog, deer, etc)
