Nice.
Might be good as well to have a link to your profile on a web client for example: https://primal.net/p/npub1ur5ju4pd0xegu7wxal543ywn3aykxmjg2c9gucvtj5aaa43sm74qcxdx2w

People not familiar with nostr won't know what to do with a qr code or an npub but this link let's them find you and experience nostr with one click.

And if you want nostr to be the highlighted contact it might also be good to have a nostr icon with the other social media links in the footer of each page.
