How to improve my looks?

I want to know how I can look better even if its just a tiny bit. I don't want to look like this forever. I would also want to know how to look less "scary" if thats possible. I also wouldn't mind a rating on how I look, and be honest. I also noticed that one side of my face looks a bit bigger than the other one? and its kinda obvious my skin is horrible but I would take any tips on how to better improve my skin.
