There's something in that awesome book I won't shut up about that really clicked with me, when the author was discussing the idea of Character Vs. Plot -- the essential point was that you can't separate the character from the plot, because without the plot, you'd have no character. The thing that makes a character interesting is the choices they make, and if the plot doesn't present them with choices that will help us learn more about them -- about what they want, and what they think is important -- there's nothing interesting to see.
We do need to sympathise with characters, but hardships alone won't accomplish that. I've talked about this before --
There's a lot of very basic, surface-level emotion in the first couple of chapters that don't tell us much about the characters. If I saw on the news that a disabled woman had her family heirloom taken by debt collectors, I'd be like "aw, man, that's awful," but I wouldn't identify with her family in any meaningful way -- we need to see who these people are in order to sympathise with them, not just that they're in bad situations. [The main character] is embarrassed when she's laughed at and she's sad when a sad thing happens, but I don't know much about her.
Thinking about specific, character-revealing choices, here's a small example:
When Celeste suddenly ends up in a fantasy world like she'd always dreamed of, one that hails her as chosen, she dismisses them, saying "I gotta go home [...] you've got the wrong person." Why? That's not a question for you to answer here on the forum -- that's me pointing out that from the comic so far, I don't understand why she made the choice to reject that world. Everything we've seen of her so far indicates that she gets lost in her dreams -- so lost she's sword-fighting at work -- but here she doesn't do that. She doesn't get invested, even though she thinks she's dreaming. She's not even curious what this whole "Chosen One" thing means.
I think that's a choice that definitely could be used to reveal character, but here it doesn't seem to come from Celeste. Instead, it seems to happen because it's the expected next step in the story, the "refusal of the call" from the hero's journey. It conflicts with everything we know about her character and doesn't seem to suggest anything new, which makes it fall a little flat.
We don't just need to see situations and hardships that evoke sympathy -- but we need to understand why characters are making the choices they make, even if they're not the choices we would make. For example, if Celeste said "No, I can't get caught daydreaming again, I have to stop doing this, I can't get involved in this," then that's definitely not the response I would have, but it would tell me something about her and how she feels -- in this case, it'd tell me that she feels like her dreaming is holding her back in her real life and she wants to be better. If she was in complete shock and just kept saying "but.... this isn't.... REAL, this can't be real" then I'd learn that her fantasies were less of a dream she hoped for and more of an escape from reality, and making those dreams real is overwhelming and scary rather than exciting. If we got a moment to see her really excited about the fantasy world, but then her face fell as soon as they said "chosen one" and she said "oh.... that can't be me. There's nothing special about me," then we'd start to suspect that her rejection comes from a place of low self-worth -- she fantasises about these things, and wants them, but can't accept that they'd happen to her.
AND SO ON. It's not that the choice she made was "wrong".... but it's an odd choice for her to make, because we don't see her motivation in making this choice, and it conflicts with the motivation we've seen so far.
The reason I say all this is because you're super early in the story, and I think that thinking about this kinda stuff can make your story even stronger going forward! This next chapter is gonna really define her as a person much more than the beginning, and as we start to see more of her motivations and how she feels about what's happening and what's driving the choices she makes, we can start to get to know her better, and that's when we'll definitely invest in her as a person. : )
