Firstly I have to say that johnny's smile is the stuff of nightmares.
Hi. Hmm, you mean technically, or aesthetically? That's my smile, I wanted to keep to the reality, you know.
What I also wanted to do, was to give it a bit of a, like my friend dubbed it, Monty Python feel -- the mouth/smiles are widened on purpose. Generally, I threw it in here just to share it with you, but thanks for the word of critique.
Cheerio!
