Creaking noise on the left side
 

Hey guys, in my 05 accord ex/v6 I have a creaking noise every time I accelerate or break, or go over bumps. It sounds like it's coming from the driver door, but I can't tell where exactly.
This started happening after my gf accidentally backed into the front left side (lol) and a collision shop replaced air intake and headlights and painted the bumper.

What could it be? The struts maybe?
thanks in advance
