A request for revision that goes for more than "This isn't what I'm looking for"? Be still, my beating heart! It's always easier for me to make it bigger, so:
You're right, the Aspects could a rejiggering. The getup serves two purposes: one, it's there to keep him protected from the heat and the work of the job, and two, it pinpoints him as Lower Class Laborer, but the name could be more expressive to suggest that.
Why Socially Downtrodden? Because it forces him into a certain sort of position and role that he's not comfortable with, but hasn't of yet been uncomfortable enough because he still believes he can get everything he wants from where he is without giving anything up. The movie audience is likely to see him as a supporting cast member or Quirky Sidekick there to help move things along-- wry, resigned sense of humor, quietly confident, helps other people bridge the gap between themselves and their desires, and that's what he does because that's what you're supposed to do. That's the way you're supposed to live that's gets you everything you want and love and need, so he does it. It's very rational, despite the groundless nature of the premises on which he is basing it.
He's put a lot of years into believing that story. It's been hard work. When that story finally fails him-- not if, but when-- is the crisis and explosion point where the audience gets to see the wrath of a gentle man and re-evaluate what has come before. He's not there yet, but he can see the edge in the corner of his eye when he forgets to be busy.
Why the Divine? In his words: "Oh, come on. The Pantheons aren't anything more a bunch of children's fables and fairy stories for a people who didn't know any better about the world. If the gods were real, wouldn't we have actual evidence about their existence? And the things of the Mist don't count either. The Nameless Divine Maker, who set the Clockwork World in motion and let us do what we will to reach them again? That's a mature faith for grown folks."
(why yes he does have contradictory beliefs about how the world works, why do you ask)
He's ready to start falling. He just needs a push, which will begin with an airship crash in dangerous territory. The main question is the one as to how he falls-- the revelation that what he thinks he wants is not what he truly desires, the realization that he can be a doormat all day and people will never think of him otherwise, the betrayal of his skill set being completely incompatible with the pursuit of his desires, the adoption of a cause and a passion beyond his half-thought-through desires of 'be the jolly folktale hero, win the kingdom'.
He's there to break, and be remade anew.
