Little late to the story, sorry, but here are my first impressions-ish: (this review is only covering Chap 1, so apologies if I say something obvious or silly that gets explained in the next chapter.)
"5 to 5" -> I can see how this is a turnoff. I personally am slightly intrigued by this, but I'm weird. Based on the feel of the setting, you're probably writing from a before-measurements-were-standardized perspective. I personally would have attached what it meant (for example, 5 (parts) to 5 (bowling pins) translating to 5 hands (stacked on top of each other like a game of sandwich) shy of 5 bowling pins. This would likely be about... 70 or so inches based on my measurement of a hand being about an inch thick because Google wouldn't spit out the dimension I wanted.) The idea is to tie this "5 to 5" in terms of real world objects that would reasonably exist if you don't want standardized measurements yet. I should warn you, however, that if you're going to use "5 to 5" or other constructions, that you're going to need to do a good job at inventing cultures from scratch, and thinking about how your society would realistically operate. This is because your audience will need to be sold on the idea of the new expressions and standards. I won't tell you not to do this, as LoliWithAGlock as done, but if you're going to do this, think it through and if you don't feel confident, don't. I do a little bit of this sort of thing in my work, Solstice, in my time system, but that's because I declared the setting to have 8-day weeks, and every month is exactly 32 days. Oh yeah, I also named the months after their ordinal position, so September 5th would be "Friday, Fifth of Ninth" (and the fifth of the month is ALWAYS Friday, due to the calendar alterations. Doesn't matter the year.)
There was one bit stylistically:
"And when you lose your teeth on top of everything else, what will you do then? Hmm, Wyrnol, what will you do then? Who will love you then?"
I would drop the quotes and italicise it, something like:
He'd never eaten a fruit. Mother never allowed it. The one time he'd made the attempt, she'd snatched it away. Her voice followed him even now: And when you lose your teeth on top of everything else, what will you do then? Hmm, Wyrnol, what will you do then? Who will love you then?
This is mostly for style though, and you can keep the quotes if you wanted to. You could also do something like:
"And when you lose your teeth on top of everything else, what will you do then? Hmm, Wyrnol, what will you do then? Who will love you then?" she had scolded.
using the Past Perfect to throw things even more in the past form Simple Past.
I had to read it a couple times to figure out that it was Wyrn who had whipped the guards. I can see it being assumed that Hey, I Have A Donkey, I Should Have An Instrument To Guide The Donkey. I would have made a sentence earlier with the whip to set it up as existing and being there so the audience goes "Aw Sweet!" rather than "Wait What?"
I also thought it was Wyrn at first who said "Unhand me!" rather than the (I'm assuming) love interest. Something I would have liked to see, however, is Wyrn flipping out when the guards (!) and Prince (!!!) changed their tune completely and utterly. Like, this is Royalty we're talking about here, and NOW they wanna play nice? I'd be wondering who the frik frak fukkity shit my parents were!!
More stylistically speaking, I feel you can benefit a lot from using Active Voice more than Passive. Take for instance:
It was a scream that caused him to turn around and see what the fuss was about. A young woman, with luscious black hair and a lean face struggled in the clutches of the guards who led her down the street.
You could probably switch it to active, and then lean on your ability to create metaphors, to do something like:
A young woman's scream wrenched Wyrn's eyes toward a beauty, luscious black hair adorning quite a lean face, struggling in the grips of two guards walking her down the street.
Gets you more in on the action. All in all, um, I think I'll be continuing this. I'm really bad when it comes to procrastinating, so don't worry too much if I don't reply (I haven't forgotten). I kinda wanna see where this goes. Again, my review is based on first chapter only, and is kinda off the cuff.
If you want to, you can find my work. You don't have to review the first chapter or anything if you don't want to (I'm also writing Chapter 25 so I wouldn't be able to execute on anything in the first chapter short of a rewrite.) It's also not my best as I originally started it for NaNoWriMo, though I am continuing it mostly because I want to.
I wish you all the best of luck and... *checks tags* You're also doing an Elemental Magic system?!! Ooooh!!! I um I might like settings with magic. Oh AND Weak To Strong! Okay this is gonna be good :3
