Hey, first of all, it is a great idea!
For me the message is clear, however, I think about updating the image on the home page. Currently, you have traditional Greece white/blue houses. It looks good because it matches the main colors from the website. But I think if you choose an image more related to relocation/expats/travel it might improve the website's message.
In terms, of navigation, I would change "Explore countries" button behavior. Right now when you click on it shows countries selector, but intuitively I would expect it to navigate to https://wherecani.live/explore/ page.
It would be nice (if it is possible) to have links in "We’ve proudly been featured in". So when you click on logotype it would redirect you to the article. It might improve the impression of the website.
I wish you good luck with it and curious how it would develop!
