Okay, so here's what I think:
Apple: Only shame is the grass. Instead of using a plane or whatever object you used, and put the texture on it, try to get to model the actual grass, there is an easy way to do it, google it. I used to use C4D, so I know this is possible. Rest of the model, the reflexion. The light reflexion isn't really 100% correct, try adding or editting the light, to a whiter one.
Console: Cable and buttons design: Cable -> add a twist on it. There is a simple funtion for this, in C4D use a spline, go to menu on top look for the twist. Don't know how to use it a couple of Youtube vids explain it nice and easy. Dunno what software you used. this is why I refer the C4D (the one I used to work on).
Buttons -> Try addin reflexion here. Way better than this IMO.
Shield: Not a fan of the darkness around it but it's good, nothing to add on it.
