Advice on rendering metal armor?

I’m working on making a picture of my girlfriend’s RuneScape character.I don’t have much experience rendering armour especially armor that is being effected by a bright colorful light source (the magic is going to be orange-red) so any tips, tricks or tutorials pointing me in the right direction will be helpful!

So far I’ve scoured the internet trying to find reference images for how Metal interacts with light but I’m coming up short in a lot of places.
