Product preview card using Flexbox

What are you most proud of, and what would you do differently next time?

I learned the basics of flexbox and got acquainted with the picture element.

What specific areas of your project would you like help with?

I have noticed the longer time it takes for the image to adapt to the layout when switching between mobile and desktop views, but I am unsure how to fix the issue (or if it needs to be fixed at all since users will generally use either the mobile or the desktop view, and the first time loading of either layout is fine).
