Congratulations on the completed project!
I took a look at your files in the repo - very good use of variables in css. Also, very good use of "ttf" files for fonts - it's always a prefereable way to implement a font.
I assume you went with the "mobile-first" approach for the repsonivity, which is a very good approach especcially for this project. However, at a desktop breakpoint, I can't see any way you can position the elements accroding to the design using flexbox. I'd suggest you use Grid for this.
The index.html file is well structured and easy to unders, I'd only suggest you use more gaps and comments for the lements to help readability (especially if other developers will be working with the code).
Also, please take a look at the paddings and the font size, because it looks that it differs slightly from the design.
Overall, once you position the elements on the desktop (I suggest you implement the grid for it) and few corrections of the font sizes and paddings, this will look very good.
