Here's ToyNetwork's 16 inch Amy Rose. Their quality goes up as they have more size to work with, but she's still got that big black eye-edge they can't seem to ditch, even though it's not present in the games.*

Here is a shot of the backs of 8 inch Toy Network Shadow & Amy plushes. As you can see, from the back they're pretty ok looking. Nothing super spectacular, but they do have Amy's spikes right, and Shadow isn't a mess from behind. It's the faces/fronts of the dolls that Toy Network seems to constantly mess up. So as long as you don't actually flip the dolls over...Granted, more recent efforts though seemed to want to improve them some what.
