I still have yet to see a miqo'te woman that doesn't look like she's from 15-23. Seems impossible to make them look older, made it difficult when I wanted to make Valic's parents (or at least a concept of what they would look like).
Personally I fantasia'd because my character before looked like he was early to mid twenties. Too immature and boyish looking as a male miqo'te, even with the beard.
I eventually wanted a character that looked more mature, handsome, and respectable looking than the average miqo'te boy. Ya know, something away from my old persona as an ignorant noble treasure hunter blinded by glint of the coin and more a sexy scholar of magic. I was fully capable of making him look even older, such as X'ruhn Tia has shown in the RDM questline, he's about 30-40+ with his wrinkles but still manages to be good looking(at least so I hear). However I didn't want anything that looked past it's prime, I just didn't want an ignorant young man... So, below are the results, before and after.
Overall, I make my character's age relatively believable and more akin to how they would act. age is wisdom, and young is more free spirited. The biggest difference though is in personality of course, as people can still assume a char to be quite young looking despite these changes. Jaw lining and eyes seem to make a big difference in it though.
Just a couple more I found in char creation ^, but as more related to the topic... Typically I leave age up to imagination until someone asks or I imply it through years of history. Such as bringing up 6 years of military service(that alone implies he had to be probably late teens to even join, so he'd be at least of 23?) then sometimes mentioning 15 years of study (5 years for each area to a degree). Casually thrown into conversation whenever it's reasonable to say or I just straight out tell them my age if I'm asked ICly or OOCly. Though of course I expect them to not use any OOC knowledge ICly of course without a good reason. Most importantly though is the demeanor that conveys wisdom and age that has other players assume he's a "man" rather than a teen or early 20's guy.
I'm probably just tired and babbling but to more accurately answer these...
How does your character (or you) determine the age of a character it is interacting with? Simply put, I don't. Age doesn't matter to me most of the time, but I generally make a broad range depending on how they act. If they're acting cute or ignorant, anywhere from early teens to late. If they're high spirited, adventurous, or sound like they've been in business a while, early 20's to 30's and beyond. I often give the same treatment to every character regardless of their age, very minor change of wording here and there but nothing significant.
Does your character find a way to work it in the conversation? Not particularly, though it can happen in casual talk. Such as a conversation leading to "how long have you been doing etc" or "when did this happen to you?". It's not a goal in conversation I feel I need to reach as like above, I just judge based off feeling out how the character is portrayed. I guess it's also because OOCly I'm a firm believer of "you're as young as you feel" regardless of your age. You act young, you are young! You act old, you are old!
Do you expect it to be tagged OOC some how? I mean, I could put it in my search comment to let someone know but I feel as though it wouldn't do much good anyways. By that point it metagames IC a bit in having to figure out or ask how old my char is and I wouldn't want that. I leave it up to perception through conversation of how my character speaks and if anyone implies I look young, I take it as a compliment like anyone would typically and correct them to a degree. It's not really an expectation or too big a deal, I'm complimented when I meet RP'ers who recognize his age simply through RP, it shows I'm doing a proper job portraying what I created in the first place.
My first persona was 23(pics above), Valic's now 28(maybe going on 29?) and so far it hasn't been too relevant of an issue. It definitely seems more an issue for female characters(race varies here) to depict age correctly. I say if you can't do it through the faces and models provided, do it through alternative methods. Clothing(glasses are a big one) can help show maturity/responsibility as well as implication the person can read a lot or is smart. I guess it's a stereotype but it works? Clothing as well, wearing skimpy stuff as compared to something more dignified and fitting of someone of age. Ragged clothes can be either way but dancer-looking clothes are probably more younger suited whereas robes and etc fancy outfits may be more classy and reserved looking. Then of course through how you talk, can vary on what kinda feel you want.
Need to sound like a wench that's had enough of what life has to offer? Pick up a lazy accent that implies you tire of speaking, sound more annoyed at life and how the years have treated the char. Imply you have some wisdom that only age can offer by condescendingly talking to people like they haven't experienced what you have.
Need to sound like a qualified scholar that likes a good read? Use fancy words, refined grammar, and visit a website that gives you a "word of the day" so you can implement it into your speak regularly. Replace simpler words you use regularly with more profound sounding ones that resemble that of someone who takes time in understanding vocabulary and reading to such a degree that it's used by their own tongue. Talk about stories or what you read and how often like you've had experience in reading it for ages and adoring doing it ever since you were a child.
In the end, I find personalities paint the picture better than the models we have in game. The key concept being in "experience" to depict just how old your character might/could be.
