You're only 170 cm (5' 7")?
Well, you're only 15, you still may have a growth spurt left in you.
Male models typically have to be at least 6' (183 cm) especially for catwalk/group photo shoots with other models.
You have the look, I'll give you that. Characteristics are practically meaningless in the fashion industry, it all depends on what the agency you work for and/or the client who wants to book you want in their models. With your look, I can see you doing American Apparel, Urban Outfitters, etc.
With your height now, I don't see you working in the model industry.
That's my professional opinion for someone who has friends in the industry.
Just so you know, modeling is not just putting on some clothes and strike poses for the camera. It's work, it's tedious hours and VERY competitive. On top of all of this, male models make half, yes that is correct, half of what female models make. It's barely a living, so if you think you can go into this industry expecting you'll make it big, you need to think again. You have to be nearly perfect and quite the chameleon to make it in modeling. Your height is already working against you, on top of that, as handsome as you are, you would only work for a select amount of looks. You need to work on your body, it is thin, but not built. Male models are to be built but not body builder, thin but not effeminate. You get what I'm saying.
Now that I gave you my professional opinion, I'm going to give you my personal opinion:
Look for another passion. Modeling is a 10 year gig at it 's max and that is only if you are wanted enough to get consistent bookings.
