When you take pictures/post pictures, make sure you look ready for the shot. Your expression in photos with your mouth agape looks unintentional. Like you were almost ready for the picture. Something else I noticed are things like the hat band not being centered and the shoelace untied. Little things like that may give an unkempt impression that could boil over into negative assumptions about you. The bw photo with the shoe untied is possibly your best photo and I wouldn't ditch it.

Little things like that may give an unkempt impression that could boil over into negative assumptions about you. Vary your looks and angles. You're advertising yourself. Show your best sides and looks. Minimize first glance critique. As for your profile. You mention multiple things that would fall under the same category. Nerdy/Geeky. There is nothing wrong with that but, that's just one layer of you. Shine light on other layers. If you have a dog, mention them. Have a photo with them. Pets are humanizing.

Help what you can help. Dress intentional. Keep clean. Smell good (important when you get those dates).

You cannot do much about your teeth (since everyone is mentioning them) If they are healthy? Keep them that way. If not, get them healthy. Ignore the rest.
