I understand your point, however a literary analysis wouldn't be critiquing wording, that would still be technical critique.
If you were to make a critical reading of this same hypothetical panel, you wouldn't approach it as "this is bad wording" you'd approach it as "why was this wording used?" it could be to imply a sense of urgency, there could be a reason someone would talk like that, the broken-up sentence could imply something about the character or situation.
Now, of course i kmow that in this case, it wouldn't be deliberate, it would he due to poor writing skills or poor English skills, but the comics I'm specifically addressing are the ones, where a critical reading would actually make sense.
Maybe in this hypothetical comic, the main character was always wearing a pearl necklace, I could try to analyse possible meanings for this, like decadence and decay, because its old fashioned, maybe - or another view would be to say it was sentimental, because it shows a wish to hold on to the past.
Analyses don't necessarily mean going through a comic and deducing what the author meant intentionally, it's about different readings and interpretations that happen in the meeting between the reader and the media.
As another commenter in this thread said "it is hard to do this, because some symbols have a lot of different meanings" and while that's true, analyses of this kind isn't about finding the one truth of a symbol, its about taking a piece of media and interpreting it in a sensible way. A symbol can have more meanings, maybe some of the meanings fit better with the rest of the story than others, then you have a plausible interpretation.
And, as I said, I'm not asking why nobody does this, I'm saying I'd like to talk to other people who find this interesting and I wanna see their works. I hope that clears up my intent.
