does this sound and look grammatically correct?

The ruined city of Troy looked to be a catastrophic place. There was blood everywhere. Men’s bodies were cut open and infants were crying. The whole city looked as Poseidon, the god of earthquakes, gave Troy the most disastrous earthquake he had.

"looked to be" -- what's wrong with "was"?

I'd rephrase the last sentence like this:
The whole city looked on as Poseidon, the god of earthquakes, gave Troy the most disastrous earthquake ever.

Thanks so should i write:

The ruined city of Troy was a catastrophic place. There was blood everywhere. Men’s bodies were cut open and infants were crying. The whole city looked on as Poseidon, the god of earthquakes, gave Troy the most disastrous earthquake ever.

Yes, much better!
