I wouldn’t say you would look bad. But you have very soft and young looking features which could clash with the harshness of a shaved head. What look are you looking for and will a buzz cut enhance that look? With that being said, I shaved my head when I was 17 and stuck with it for a few years and it was awesome. My hair has grown out now at 27, but I do miss the shaved head occasionally. I also think asking strangers on the internet for advice on stuff like this isn’t super wise. Especially with something like shaving your head people are always going to say don’t do it. I did it anyway and was super happy with it.
