Hey Guys. As a modeller(just an amature ) I like give my stuff my own spin, from modelkits to figures i collect. In case of my Transformers, most of the time, their faces. To me they are the most important part of their character. So i paint their vizors/eyes a more vibrant metallic color topped with a gloss coat. Their face, a non metallic colour with a semi-gloss coat. It gives a bigger contrast between the face and eyes, they pop more. Let me know what you think of them and if you have questions, feel free to ask... Greetings, Sebastiaan.
