^^^ As you are the subject of this profile review, anyone else's photo status is irrelevant. I agree that your shirt is like a red flare distress signal, useful if ever stranded in the middle of the ocean. It is blinding to look at. Also a bit crumpled. Correct those things (new shirt I'm afraid), smile, and you're pretty much done. From an aesthetic perspective, bad lighting in the second photo. If you have a desk lamp, it is easily fixed. Or else take it during the day or even better, outdoors.
I find that it looks too touched up, unnatural looking. Main pic doesn't appear to me to be your usual complexion or appearance, thus to me, it doesn't work. I think a bloke looking after his skin with applications not extending to make-up (or deliberate computer generated enhancements for anyone) is sufficient, beyond that is overdoing it.
I don't know what's wrong or right with you because I don't know you. To me, it is overkill with the posing, flexing and musclebound pics. Try subtlety. Your physique already does the talking in appearance, beyond that is just showing off. I don't mind the one of you in the bush except you should be doing something natural (so it doesn't look so contrived), like collecting firewood, not contemplating starring in the next Rambo movie lol (and wow you actually look small in your military outfit). The handstand one is the best musclebound pic, it's different, and not an easy feat.
All I can suggest is to describe yourself or anything else as you would if you were talking to somebody. Scratch the surface a little. See, I was interested to hear what you said above because I learned something about you, and you weren't even trying. Knowing how someone thinks is the most interesting thing to learn about a person (to me anyway). Forums are good for that, more informative than just the usual bland narratives seen in profiles. Some people think you have to crank it up in a profile to stand out; not very realistic if it isn't how you usually are.... However injecting a little bit extra does not mean it has to be anything fancy. Some insight into who you are (personalization), as the first poster said, is enough, to reduce the generic superficiality of this process. Forgot to say, provide a clear front-on pic of your face (you can direct them to a FB page or elsewhere if you prefer).
Talk to women in real life. Go up to a stranger and start a chat, this action isn't only restricted to a club/pub environment. Meet people in real-life basically and think of the internet method as an adjunct.
If a woman is enthused enough by your self-description and pics, she will be keener to learn more about the type of woman you're interested in. And it isn't too long if you are able to generate that interest initially and throughout. Great main pic, collectively you have a decent set. The most interesting part and a great conversation starter in my estimation is that you work for the CDC!
I'm not your target audience so I may be off base. On first impression, it looks as if you have a kid. May or may not put girls off. The flag wrapped around you though nice n all (it is Irish after all ) makes you resemble a hoon. Sunnies aren't a problem as you have another pic (in the suit) where your face is clear enough, but another close-up without your face obscured wouldn't hurt. Personally I like the motorbike pic, you're a 21 yo guy so having a toy in your pic is about a given. However telling people about the rides you possess (subaru and mentioning your motorbike twice) makes you come off as a show-off. Maybe girls your age like that, who am I to say. You should talk more about yourself in my opinion so we get a better understanding of who you are.
I only have a comment on the pics. Your hair in the bunny ears pic gives you a severe appearance, I'd rather see how your hair looks framing the face. Best pic is the 4th one widely smiling with the dangly earrings. I also quite like the one with the blue checked cap, 5th pic left of shot.
I agree about the gold chain looking as if you're being hung but in regard to this quote, we can be biased about ourselves and miss seeing things others do, so I think this was a nifty piece of insight given not only to the TA but to others who wish to contact him. At least a girl who goes on a date with him will know it doesn't necessarily mean he is aloof and disinterested. I heard of a guy who constantly looks stoned, but it doesn't reflect what's going on inside, it's just how he looks. Your profile gives a good general idea of you TA. Most appealing aspect was your demonstrated tact, flexibility and possibly humility, making you appear approachable - this I believe is the most important trait for dating profiles, especially for men to help improve the odds of receiving first contacts.
