HoMM VII Haven Units – Haven faction units from the seventh installment of Heroes of Might and Magic.

The manticores in the screenshot look a bit too "blurred" and "fat," as if their body parts have been enlarged relative to their bones.
Regarding the animations, I already mentioned that FrozenSol fixed them. If you plan to further refine the manticores and release them, it might be worth collaborating with FrozenSol. If you're just posting screenshots to show them off, then it probably doesn't make sense.

Well, I'm not sure when I was choosing the dimensions based on the original size of the unenhanced manticores from Heroes of Might and Magic VII, I got these results: the legs turned out to be too "small," and everything else was more or less normal, or the legs were slightly small, and the head and everything else were larger than usual. (By the way, the enhanced version differs not only in the head and tail but also in the wings, for which separate bones are provided).
