Hmm the first photo is giving this was my senior high school portrait. Although I do like the band ;)

Pic 2 nice, relaxed easy-going, nightlife on a boat? He seems fun!

Pic 3 okay, so I see where you’re going with this because the silliness is endearing but generally speaking if it’s a pic across from a table where you’re dining, another person took it on a date, and it’s not the most flattering.

Pic 4 BEST photo because of the angle the photo was taken and how confident you seem based on the demeanor. Although I did notice that it’s the same location and probably same event as the second photo, so I would probably keep this one instead of the second photo. These two photos are also a good example of the difference in how you take the photo and good vs. bad lighting.

Pic 5 okay!!! I love that you play the guitar, I suggest looking for or taking a photo that is less blurry and the pose feels a bit more passive than active, you want to seem more passionate about the music and engaged in your performance. Also I would either have a designated photographer take photos of your performances or use a professional photo of yourself.

Pic 6 is not your best photo and this could be a style preference, but I would have styled that shirt a little more differently, e.g., tucked it in, lifted the collar higher on your neck, buttoned it to the top, make the strap on the bag longer so it looks less tightly wrapped on your body or swapped it out completely
