That Azurobe model really gets me. If you look at Serperior, it has that collar that's effectively a second layer of the body, so the body above/"inside" it is thinner than the body below it. If you remove the collar, there'd be a discontinuity between the two sections. And wouldn't you know it, Azurobe has a shitty-looking ribbon slapped on the neck right about where that discontinuity would be. If they had used the Serperior model as a guide for proportions but made the model itself from scratch, there'd be no need for that ribbon to be exactly where it just so happens to be.
I'd really love to get my hands on these models and check out a few things.
