Yeah, they're quite cool. Although some things look low-res. Like the Rev meter, and the Monster logo on the green screen.
They're also a bit normal, just some logo's on them, and that's it. You should try to make some design instead of just adding logo's and stuff like that on it. It gets cluttered that way. I am not saying yours are. But yeah, they're cool, but you could work on some designing maybe. I hope I helped you out a bit mate.
Thanks for complimenting my render skills, hehe. If you want anything else rendered, just ask me.
