Guns should be fire colours and transition to ice where the left hand meets the gun. I like the kabalites ok the left the most, and think if you worked with that on the characters they’d look cooler. Maybe even have the two colours converse to bright hot white and ice cold white in the middle of their armour?
Eyes: either both gold
One orange one blue
Or lighter purple
