Does my site look professional

I have finished building my site using the “Fictive” theme and absolutely no CSS changes as I have been skating on very thin ice throughout this build. While the site is in english once I have had constructive advice from this request I intend to change it to german as I am based in Switzerland. I am happy with the theme and the look, but I have no idea what an experienced developer or web/blog expert would think about my site. [ Link redacted ] I am a pensioner and not a technical person by any stretch of the imagination but I do need some sort of professional presence out there. Please any criticism advice would be welcome.
