What's his ascendant

I'm dating this guy, let's call him Stephen. I know his birth date but I do not know his birth time. He looks a lot - A LOT - like Motley Crue drummer Tommy Lee, especially in the photo I have attached.
In fact they are related, this guy's father and Tommy are cousins.
Here is Stephen's chart.
What could his ascendant be taking account the photo?

He's gonna ask his mother for his birth certificate as she is not sure of the exact time. We'll know in the next few days.

What do you think his rising sign is ?
Any guesses ?

I think the moon usually gives an indication of looks... it's in the eyes.

Moon in Scorpio has intense and somewhat scary eyes, and Moon in Leo has big bright cheery eyes with some sparkle, etc.

But yes, finding the accurate birth time is a good idea! Rather than guessing the Ascendant.
