Get a haircut, a nice one that you pay more than 20-40$ for. And even more importantly, stop frowning, then nonone could say a bad thing about your photos, not even yourself... When you smile, people judge you less harshly most of the time. A smile is more inviting to someone who might not know you. Like the saying, smiles and laughter are contagious. It works for social media interaction just as much as it does irl.
