This was a lot of fun, the thing I found most challenging was dealing with the background image going behind the header. I had originally use absolute positioning to get the main content area to go behind the nav, but later ran into problems when I built the footer. I instead opted to make the header fixed, which would end up taking it out of the flow of the document rather than the main section.
Also as another user noted the asset for the mobile snippet is not present in the download files (I did not have figma access).
All in all a great way to spend an evening!
Great job, my only comment is to have the hamburger menu switch to an 'X' icon when active!
