Well, lots of advice so far.
The problem involves the idea that what Amber sees is different from what the other characters see and conveying this from the page without inducing confusion and doing so succinctly.
Your attempt (above) tells us what amber sees but it doesn't tell us what WE SEE, and that's an all-important consideration. You probably assumed that your description at least implies or infers that WE SEE what Amber sees, but that's not what it says; it says, "Amber sees" and leaves us high and dry.
This would require some real scrubbing to get right, with any number of different approaches written and tested out.
Of the top of my head I think I'd try the POV first.
EXT ANCIENT CITY - DAY
Amber and her friends amble along a street and into a plaza-like situation where statues and sculptings abound, all showing the same signs of extreme age that everything exhibits.
Amber checks up, appears to go trance-like. She gapes.
WHAT SHE SEES
The statues and sculptings alright, but here they are as new, as they were five-thousand years before, in all their glory.
AMBER'S FRIEND (VO)
Come on, Amber, we have to keep
moving.
AMBER
No, I -- give me a sec.
AMBER'S FRIEND (VO)
You okay? We're going.
AMBER (VO)
No. I'm fine. You guys go ahead.
I'll catch up. I just need a minute.
BACK TO SCENE
Amber's friends move along, leaving her staring. She shakes her head, blinks her eyes, shades them with a hand from the sun, disbelieving, puzzled.
Amber runs her gaze around the plaza again.
WHAT SHE SEES
This time everything is as it is, statues and sculptings worn with age.
BACK TO SCENE
Amber runs to catch up to her friends.
AMBER
Hey you guys, you're not gonna believe this!
Amber catches up. Her friends turn to her.
FRIEND
Believe what?
AMBER
What I just saw.
FRIEND
What did you see?
AMBER
I, uh, well -- oh never mind. Let's go.
NEXT SCENE
This would be my first attack but probably not the last.
I don't think there's a blessed thing in the world "wrong" with declaring POVs like this, and in the end if I decided this approach was gonna be it, I'd not hestitate a moment writing them.
You have some writer's work to do. Play with this, write some renditions, keep looking until you find something that suits the scene and your voice. It's there, you just have to find it.
Study the responses you've gotten here, there's good thinking in them.
Cheers!
