Good looks on putting up a video.

You need to relax more. The reason you're coming off as a "jerk wanna be player" is because you're very conscious of how you look. One of the reasons it's easy to tell is that you tense up your body when you're moving. This might be because you're also nervous for the video you're making, but assuming you're not:

You can see that you're moving your shoulders to the side of the foot you're stepping with. If you don't know what I'm saying, some people say that it's the cocky limp. Nonetheless, it could also be attributed to the fact that you're wearing three layers. I would suggest to relax your shoulders and practice walking. Widen your steps and pace and keep your head up.

Your smiling approach does smell like a stereotypical alpha. It's not bad at all; you just need to loosen up your body. Your whole body also turns when you turn your head. Best advice I can give, although not too practical, is you have to be more easy going and relax your body.

Stop wearing so many layers and clean your room.
