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

I'm most of getting the grid layout to work. I never really worked with CSS Grid before so when I realized I had to utilize for the challenge I got a bit nervous, but after a bit of trial and error and learning about "grid-template-areas", I managed to get site to resemble that of the design. Still need to work on my naming scheme though.
