Alexstrasza's model is wrong

In WoW Alexstrasza has copy of blood elf body. Maybe it was just a game restriction, but here is the thing: Alexstrasza in all official arts has the same shape. And, what is more important, not just in pictures, but also in books and HotS cinematic trailer of herself.
You can say: but she is a dragon and looks like she wants because of magic. Yes, you are totally right, but there is no information about her desire to be like Zarya. In books she loves her elven body, and by this time we also have no information about bodybuilder-like elven women. And I'm not joking about differences. Here is the comparison of cinematic Alexstrasza and in-game model:

Distortions by perspective on these screenshots are minimal, accuracy not brilliant but not worst, so nobody can deny obvious differences.
Game features? No. Here are other warcraft female elven bodies from HotS (Valeera, Sylvanas and Tyrande):

These elves have the same type of shape with Alexstrasza in warcraft universe, but for some reason in HotS dragon has an entirely different shape when other elves have similar.
Why is this bad? Not because I cant fap on it if you think so, no, cause I can. It's bad because it isn't Alexstrasza's shape, and game style can not explain why she got it.
If you keep reading my post, I wanna show you some concept-arts of Alexstrasza:

At pic 1 and uncolored version shape is normal, looks like other elves from HotS. But on colored versions of second photo for some reason we see that the body became much wider than it was in uncolored version. So, here is my hope for the model: artist painted picture with low accuracy, and paints came out of the contours. Then 3d-designer based his model on only first two colored pictures. I expect that he don't know nothing about prototype, so when he tried to make shape more proportional instead fat body like on broken concept, he actually did this but in a wrong way and he designed something more like Sonya or Zarya shape instead slim elven body.
