I don't know about soul, but the new models look too bulbous and their fingers have Jimmy Neutron finger tips. (Amy's model looks particularly bad in this regard.) Sonic always looked better when his hands were more or less normal human hands, not these gigantic cartoon catcher's mitts. There's not enough hard edges or contrast too, but that's more of an art style thing.
The Heroes models aren't good either, though. Sorry. They're a total step backward from SA2's. Which, frankly, were a downgrade of SA1's. I will take lots of goofy facial expressions over almost no facial expressions any day of the week, thanks.
