Social Proof Section using CSS grid and flexbox

As far as responsiveness does it look good on most device screens? Also I was confused on how to use grid and flexbox together, so is it best to use both or just stick with one. I used grid to get the overall layout and then used flexbox to adjust the ratings and reviews section to look similar to the original design.

I'm also learning how to be more organized with my scss files so if there's any feedback on that I'd love to hear it. Thank you to everyone who will even just look at my solution, and looking forward to any feedback about my solution!
