Responsive design using | CSS Grid | Flexbox | Sass | Javascript

I used scss in this project as practice because i haven't used it in some time, it was a lot fun to try to get as close as I could to the original design and make it look good in all widths to be fully responsive. Sass mixins didn't work for some reason so i just split the breakpoints to different files, maybe there's a better way of doing this without mixins, althought using mixins would have been way better. Anyways whad do you think, have I done a decent job with this project or does it still need work? and any advice would be much appreciated. Thank you 🙂
