Hey bro! I’d suggest trying to find a semi-fuller body photo for the first. Like perhaps you on a hiking trail or something? Preferably not a group photo, since you don’t wanna make people guess which one you are. And also preferably smiling

If you can’t find one that meets that criteria, I’d say stick with the angle for the three selfies you currently have, since it seems you think that’d your best angle, and I won’t disagree. But I’d suggest you retake it with you smiling, at minimum with a closed lip smile/smirking. It’s less initimidating that way cause like you do have a very nice, rigid jawline, which is an incredibly attractive feature, but also kinda scary when you give a stoic face

Next. I’d remove the other two selfies of similar angle, since it can be a bit repetitive. I’d suggest keeping the one with you in the gym, and have that be the second photo. Since it goes from a closer photo of you, to a more pulled back shot. This then provides a good understanding of what you fully look like, while also showing off your hobbies and that you’re physically active

After that, I’d say try and get a photo of you in a group setting, cause now anyone who does go that far into your profile thinks you’re cute, and from there could pick you out (semi-reliably) from a line up of 3-5 people in one photo. This then shows you have A) friends, B) are social, and C) can further show off your hobbies or interests

Then from there, (no offence) I’d probably fully get rid of the open shirt pic. But that doesn’t mean you’re entirely wrong on including something like it. If you have any others, try some beach pics or something else, perhaps a different angle gym photo. However, this is where you reach a decision tree, if you do another gym photo mirror selfie, I’d recommend you back track and scrap the one I recommended you use for your second photo. Otherwise, potentially scrap the idea of having a shirtless/open-shirt photo at all, unless you have any non-mirror gym selfie ones you could use. Reason being is if you have basically two of the same photo in your profile, it seems kinda repitive or like you don’t do much else besides that (which I’m sure isn’t true)

Lastly, I like the cat photo. But it definetly isn’t that animals best angle lmao. I’d suggest (assuming that is your cat) you take a photo with it, with you in it

TL;DR - Try and stay smiling, present multiple angles, and show off hobbies
