DeUna! - FinTech 404 Error Page

You’ve done a great job setting the foundation for this 404 error page. Right away, the design feels approachable, clean, and in line with DeUna!’s brand. The color palette works well, the message is easy to read, and the 3D illustration adds a nice visual touch without being overwhelming. It’s clear you paid attention to the brand’s tone and style.

Now, to take this from good to great, here are a few areas to strengthen—just small shifts that will bring the design closer to the brief.

The headline 'Oops! There’s been a mistake' is a good start, but you have an opportunity to be a bit more helpful to the user. Try adding a quick explanation of what went wrong and what they can do next. A simple line like 'The page you’re looking for doesn’t exist. Try searching or head back home.' can make the experience feel more complete and supportive.

Adding a search bar was a smart call—it’s something the original site didn’t have, and it shows you’re thinking about usability. To build on that, the link to the homepage could be more visible. Turning it into a button or giving it more visual weight would help guide users more clearly. You might even consider offering links to a couple of key pages—something like 'Contact Us' or 'Our Services'—to give users more ways to stay on track.

The illustration adds a nice personality to the page, but right now, it’s pulling a bit too much focus. A slight resize or repositioning could help bring the user’s attention back to the message and the next steps.

And one more thing—you’ve kept things clean and clear, which is great. But the brief invites a little personality. If DeUna!’s tone allows it, try weaving in a bit of charm or light humor to make the page more memorable. Even a small sentence like 'Looks like something went sideways. Let’s get you back on track!' could do the trick.

You’re almost there. With just a few thoughtful adjustments, this design can fully deliver on the brief. Keep going—you’re on the right path.

Great job, Cristina! You've iterated well by repositioning the search bar and introducing a dedicated CTA for redirection. However, the copy could be more specific and rewritten as a system acknowledgment, ensuring users don’t feel guilty for selecting that option.

From a UI perspective, the CTA’s shape appears slightly off due to inconsistent border-radius. The search bar could also benefit from additional padding for better visual balance. Be sure to double-check the alignments. Overall, the large text here is drawing the most attention.

Keep up the great work! 🚀
