[ ] 1: Our font sizing convention is a bit out of touch between the components. For improved readability, I would offer to refer to global size of 24px, as well as increasing size accordingly for the subheadings/bolder text.
[ ] 2: As with all of our widgets, mobile view is to be implemented for cross-device capability of our website. Using media queries, the simplest implementation would be to set the flex-basis of your two main widget subsections (summary-left, review-list-container) to 100%, or tinkering with the alternative grid system offers (as that is what you mainly used).
