I love the way you made the dynamic morphing, despite my dirty mind seeing suggestive stuff. I would say, however, that there may be a bit too much "regularity" in the helmet, and not enough of the organic and chaotic amalgam of infested flesh, especially on the "bladed" parts of the helmet.

Perhaps adding a bit of asymetry, without losing the "hard shell/chitin" you've given already, would blend a bit more with his body. Just my opinion.

Voted "yes". Need more Nidus Tennogen, and this happens to be one I personally like.
