Hi! Couple of notes. (oops, and then i wall-of-texted)
Firstly, you may want to give a couple more details on the appearance. This isn't a requirement, just so people know how to describe you.
Personality and motivation - these are perfectly fine to have, but you're going to want to think about how that plays into him actually getting involved in the plot. Do his Survivorist beliefs mean he wants everyone to survive and he'll try his best to make that happen? Maybe he doesn't care about people he considers "beneath him" other than to be suspicious of them, but will he work with others if he needs to? What would make him do that?
Merits - we're going to switch the major and minor there, bronze Compounding is not a minor merit in this case fast talker is fine for that though, and having a good eye for noticing things is a fine normal merit. You have room to add a couple other minor merits if you want to, though I'd recommend making sure they actually fit with the character you're building, and aren't just random powers or skills. Why is Sonyr (fun name btw) good at what he's good at?
Being suspicious of being is a start on the flaws front! Definitely can impact his interactions with others negatively. However, we generally like people to have multiple or more complicated flaws - maybe add something external or outside of his control in addition to this internal suspicion? If you plan to have him grow out of the suspicion, what else will stop him from achieving all his goals immediately? Is there anything he is bad at doing? Where are his struggles? This part of a character can be just as much fun (sometimes even more!) to write as their strengths.
Relationships section - good start! Who does he know in these criminal organizations? How many are there? Does he have enemies among them? You say he's a librarian, expand more on that. Who are his coworkers and how does he get along with them? Do his neighbors not like him because of how standoffish and suspicious he is?
Residence is a pretty simple thing, you could just say he's living in an apartment somewhere, this doesn't have to be complicated.
Backstory is extremely short. It doesn't have to be a novel, but more details would be helpful - what criminal organization and where? Why'd he leave? Why do they haunt him? Is this related to him being suspicious? What do you mean when you say he spends time with books? How did he get this job, has he always been interested in libraries and books or is this just a job to get away from the criminals? Why do they haunt him? How is this loose end relevant to his life? What do you plan to do about it?
Honestly, some of these would be fine. You don't have to put exacting detail into your relationships section, plenty of people have their characters just not know anyone very well. Residence is also a small thing. It's looking at it all together that shows there either isn't a lot of thought put into this character, or there is, but you aren't sharing it. We can't read your mind on who your character is; you have to tell us through this and show us through RP. Sleepy no-nonsense librarian is a good start!
You've got an okay base, but you're going to need a cohesive draft to add info and make it all work together.
