Looks pretty good to me, congrats! In the desktop version, the only thing I don't like is the top menu. It reminds me of web design in the late 90s. That and the fact that the header background and hero image don't go too well together.
Weirdly, when I look at your site in responsive design mode inside my browser, it looks completely messed up. On the other hand, on my phone, it looks fine. If I were you I would quickly check the site on different devices and different browsers to make sure it looks good everywhere.
Personally, I would also make the button for the Facebook Messenger
