I(20,M) have been told many times indirectly I look older, more masculine,intimidating, unfriendly, serious and it’s affecting my social skills in my university abroad

Hello, I have been in a university since a month. To be honest, I thought don’t like to socialize a lot with people. But I realized that while studying abroad, I want to socialize with people and be at least friends and know my name. But I come from another culture, another way of making friends. But I noticed many times during my interaction with people that they feel I am intimidating, unfriendly and/or serious to them. I am in Europe. I have a beard and different clothing style and hairstyle. I don’t know if it’s a good thing or not. No one approaches me unless I do. I feel like I am doing something wrong without realizing it. It’s not affecting my self confidence but affects me a lot socially. I am 5ft10’5 so I’m not that scary and don’t know why people say such things. I just want to have fun there like everyone else. The only pro of such a thing is I have a hell lot of hot girls looking at me or noticing me there from different classes. If anyone has an advice for the problem I told you about…
