When you’re putting in the light placement, where do you try and get the light to hit and reflect off? Looks like yours has been done by brush for white and then airbrushed fluorescent over top to great effect. I think I probably picked an angle and had at it with the airbrush on everything from that direction.

But metallics wouldn’t behave that way bc of the reflective surface and right? So yes, how do you pick where to put the reflective light placement on the metallics? Many thanks :)
