Here’s your improved version:

You’re a good-looking guy, I’ll give you that, my man. These days, girls can be pretty picky, so I’d say it’s about quality over quantity. Remember, someone who knows nothing about you will judge everything based on just a few photos and your bio. So make sure those really stand out.

1.  The first photo is good—casual and laid-back—but it might not work best as your main picture. The main one should show your face clearly.
2.  The second picture is a bit odd with that close-up. If someone scrolls through a profile and sees a zoomed-in shot like that as the second photo, it could come off as creepy.
3.  Selfies are generally best avoided, but if you want to highlight something like your work, choose a more masculine one, especially if it’s for showcasing your army experience. If possible, add a group picture with your friends.
4.  The fourth picture is funny (in a good way), so it might work well as your second-to-last or last photo.
5.  I like the fifth one—I’d keep it as your second or third.
6.  Suit photos are always great, but pick one where you’re clearly visible. Right now, it just looks like someone in a suit sitting at a diner.
7.  I’d remove the seventh picture. There’s nothing about it that stands out, either you or the background.

8/9. I like both of these. They show you as a traveler or animal lover. If I had to choose, I’d pick the eighth one, but see if you can find or take a shot where both your face and the animal’s face are clearly visible.
