Lloyd Goldfine: If we do decide to make the turtles different sizes and shapes, what are your feelings on who's tall, who's short, who's wide, etc. Personally, I'm not so sure we should do it at all, but we are going to (quickly) look at it. For what it's worth, I had Leo as the tallest of the group, then Raph and Don at the same height with Raph being considerably more muscular, and Mike is the shortest. Peter Laird: I don't feel that radical size differences are really appropriate, but if we made some minor ones, they would be along the lines you mention. I like the subtle differences that Will Meugniot did for the WB project.
