Yeah, absolutely correct. The proportions are way off. And that's in sync with all Warhammer Fantasy character. If you pick up any of the Warhammer miniatures, you will clearly see the proportions are scaled to a very stylized appearance with larger heads and squaty bodies. I assume the reason is much like you see in animations, so that they read better at smaller scales and from a distance.
So the Hydra proportions are clearly on par with the established parameters they have created.
Guess I'm a fan of the spiker/evil look of the previous version. The new head just looks like a generic lizard, almost "Barney" like.
Which is a child's mascot and which is supposed to be a fearsome Warhammer creature?
