Sci-fi is about the future, and the future is about human augmentation. So I try to add gadgets that enhance human capabilities but seamlessly for into the human form. The more advanced the race, the more seamless the attire and equipment. BTW, the green character, I created the green material by modeling it in 3D and creating my own matcap by picking the colors from a jade beetle photo, painting them onto a sphere to make the matcap, and applying it to the suit. If you go to the Weapons page, and scroll right you'll see the same matcap on the green gun.
