Ultimate Flash Face is rather more realistic, and is remarkably flexible. I think my self-portrait here is pretty close.

The choice of parts could do with being expanded, I couldn't find any suitable short, curly, female-looking hair... and the mouths tended to be far to serious for me. But overall, I thought this was a fun one to play with.
Especially the bit where I could make my face thinner... and all without giving up chocolate!
