Just started using Keyshot a couple months ago and man has it saved me. Its so simple and so quick, yet creates amazing work. Still trying to get better at the lighting, but its a work in progress.
Here are some product renderings I did at work
1. Modular ramp on portable classroom
2. Scooter lift on vehicle
3. Graphite Fiber Wheelchair ramp
I would say your renders are perfectly good enough for most presentations - but it's good that you are pushing yourself, No Limits !!

Welcome! You're off to a great start!
Be nice now to see the mobile home in an environment, which will really kick it off.
Perhaps just a tad of specularity ("shine") to the car tires? You did a good job on the white, which is always difficult to achieve.
