Pic 1 must have face or you are considered ugly and generally insta left swiped.
2 is deer in headlights look
3 is no face again so no good.
You're not bad looking you can do much better. Clear skin, lean, seemingly tall, you can win here it's just a matter of time

Also do girls even like pictures of guys with guitars? I feel like it's the new fish pic. Pic attached is my profiles guitar pic for relatability and criticism

Not good bro, the pictures are all pretty bad quality, the angles are a little strange and I don't think this displays your "good sides' so to speak. The only picture I kind of like is the first one but all the other ones are shit. one of them is in what looks like your bedroom, the other is a strange mirror selfie and you don't need two pictures of you playing guitar. I would recommend you go out with a friend or two and do a photoshoot for Tinder pictures. Check out Alex's video on the PlayingFire Youtube "Ultimate photoshoot guide" and it should help you out a ton. Sorry if this was harsh bro just trying to be honest, goodluck my g.
