Welcome to MM
You say you want agency work, although i worry your height just wont cut it, most male agency models are tall, and i mean tall, but you are the same height as me, put me in heels and i will dwarf you.
You need to be taller than those female agency models out there especially when they put heels on.
you need to shoot a lot and understand your own abilities before even considering thinking of agencies so you might want to take that off your profile for now just until you are more established and people are booking you left right and centre.
Hope this helps
