Your file system of placing all these files within `assets` is interesting. Typically assets like these will end up in a `public` directory when pushed to production. Is this a framework convention? 

For the sake of this assignment, I would suggest placing all assets into a `public` directory and then contained within would be `stylesheets`, `js`, `fonts` and `images`.

Since you are using Sass, this would be the only thing that would be in an `assets` folder as these are processed assets. 

Then for your reference to the font files would be absolute `/fonts/` not relative. Depending on the framework you are following, relative paths to assets can cause more issues then solve.
