Hint: Design a 404 page. Does it suit the brand's style? Is it user-friendly? It might sound mundane, but not evertyhing can be flash or glamorous. Every day millions of people will be landing on 404 pages. You have an opportunity to help them in a way that's useful and asthetically pleasing.(It's up to you!)
A 404 page can sound like a boring thing to design, but it doesn't have to be! I experimented with a sort of neo-brutalism style that seems to be all over the design world right now for a webpage.
