Social Proof Section using Grid and Flexbox

I mostly used flexbox for this, with grid just for the desktop body layout. I found it very helpful for practicing my flexbox skills in learning how to apply the align-self property, as opposed to individually offsetting the position of elements! This definitely made it easier and quicker to modify for the mobile design. I know I could improve the accessibility with better sectioning of the elements, instead of all divs. I'm also not sure if I properly applied and positioned the background images, mainly for the mobile layout. I'll welcome any feedback 😊
