Could be a good portrait for a zerg unit or structure (such as Sunken Colony), too bad my mod is at the limit for the moment.

Alright, this is pretty high quality, although I would not use it as a hydra replacement as it is set up. Rather, here's my idea: A new Zerg unit, can be an evolution of Zergling as SC1 doesn't have any. Ranged anti-ground. The large "Eye" makes it a plausible detector, although the portait will need to portray it. To use it without extending lists, we can merge the Birth and Death anims into the same GRP; just that the Iscript will have to change for it. This prevents using three image slots. So you only need the unit itself and the shadow (because it needs a different sprite render mode; you can bake it in the same GRP, but will still need its own image entry nonetheless)

what's fixed about it?

Cool and underrated, only bad thing is lack of variety in anims
