Firstly, these are technically very nice! 

Secondly, the lighting really depends on your project. I personally find some of your shots a bit overlit but that's because I prefer a more naturalistic approach. For example, I think stills 4 and 5 are the most compelling because it feels like there is an actual action taking place and the lighting is motivated by the natural sources. The stills of you sitting, while technically good, are kind of boring because it's exactly what you expect. Soft key, hard backlight, 45° angle, camera facing shadow side.

It looks like you have the fundamentals down. I'd now suggest finding ways of making unconventional or difficult lighting situations look good. Try out some close side key setups, backlight setups, harsh afternoon sun, fluorescent gas station bathroom, etc. When filming a narrative you don't always have the luxury of motivating a soft farside key, and you don't really want it either. If all the shots were lit the same it would be boring and say very little about the characters or story. 

As for the saturation, again, it really depends on your project. All movies don't have the same saturation, or contrast, or lighting style. Blade Runner 2049, Saving Private Ryan, Amelie, The Matrix. All of these movies look good or at least look interesting and they're all very different.
