Oh I see you set everything to smooth. Look out. We got one that listens here. \o/ Now all you need is detail, detail, detail. Look at a random electronic device around you and see the detail. Need screws, maybe rubber slips gromet thingies to keep dirt from getting in the joints, scratches, stuff like that. When doing this kind of stuff it is very tempting to do what you could never do in reality, and that is make something perfect. Nothing in reality is perfect. Plastic has parts that hang off that should have been cut and smoothed before leaving the factory. Metals have dings and scratches, glass has IOR imperfections and water spots from the hard water that hits it when the sprinklers go off in the morning. Oh one other thing that will really bring out your renders is HDRI environment maps. They’re real easy to find and use and add a cubic ton of realism to a render.
