Hi
Here's a few improvement suggestions
- the logo is the most important content on the whole page and youve currently hidden it from search engines and screenreaders. That alt cannot be left empty
- the app image is arguably really important content too, but the image description is empty
- could some other images in this be background images perhaps? Just an idea
- the email address in the footer needs to be a mail to link
- the social media icons are never just icons, you'd expect to click them, right? So they need to be interactive elements (anchor tags) that also have a label available to the accessibility api (eg. Sr only text)
Good luck with it
