9 Introduce reflective surfaces
Sci-fi design and hard surface design usually go hand in hand. Adding reflectivity to those hard surfaces helps to convey a sense of realism. Think of its surroundings and show hints of that on the surfaces. The amount will depend on how reflective the surface is. Chrome, like a mirror, has highly reflective properties while brushed metal will have less reflectivity. It’s important to note that by adding the colours and tones of the environment on the mech, it helps to gel the overall piece together.
