I must admit, I agree with helm. In the second picture of Optimus, the lowered arm also looks like it's connected to his leg in that pose. You can't really tell. I mean, sure they look cool transforming all those bits and pieces, but still, not so readable as a truck. Heck, even Megatron is just an alien spacecraft in the movie. As for the avatars, they are pretty sweet. The black ones, (Yay for PSP!), are a bit less readable than the others, but still pretty good.
