60’ Darkvision because archetype.
It is clearly the chimera. You can make out the lion’s head. There seems to be another head looking down to one side. It’s hard to see in the darkness from where you now stand, but the head protrudes from the back. It could peer over the lionshead’s bushy mane you suspect.
About the lion. His eyes are more curious cat than predator. He is not about to pounce to kill you. His paws are badly cut.
The goatshead continues to look down to one side. Its antlers are strange.
The goatshead is ~60’ from you, so at the very edge of your darkvision. And you can’t make out the hindquarters or tail. I actually didn’t think of that when positioning the creature 50 feet above. I did not anticipate the plausible third option (this time)!
