Too dark. Use more contrast, and avoid true black. Most of that will just look like dark blobs at a distance. That last thing will just look like dark little geometric shapes with vague blue areas.
And use preshading- lighten upper surfaces more. You're doing a great job getting the basics right, but if you don't light things right, it'll look pretty bad in-game- just dark things with some glowing bits. Sorry, I know that probably sounds harsh- but details alone won't get you where you want to go. Preshading is really easy- if you want me to take one of these and show you, send me the model and the skin.
And the crowd is right, for once. OTA models that you didn't make, reskinned, are probably violating copyright, although that certainly gets somewhere into the gray area. Can't blame you for wanting to try, though. Good luck with your work
