I'm glad it was helpful!
I feel your pain.. I had a bowl of soup in front of a character in a thing I did.. and I drew it and thought okay.. looks good.. I went back and looked at it carefully the next day and it was changing size, position, etc.. When you have a bunch of panels where the character is in roughly the same spot, those continuity issues really creep in. I think you said you were involved in animation at one point (sorry if I'm wrong) but to me it's like the same idea as a moving hold. The longer you have a hold frame the weirder it gets. I did learn a trick for maintaining consistency in relationships of distance but it's kind of hard to explain without doing a really detailed tutorial.. To summarize, you take a visual reference from both scenes and create a grid from your vp off of the item in both panels. Scott Robertson describes it in his drawing book... I just tried to type out the rest and it sounded confusing as hell..
The 180 thing... I typed up a long thing but it was getting long-winded and into things that really don't matter here.
Hopefully this explains better than my words could've. Yes it's film but it's been widely accepted in comics AFAIK.
We're establishing an action line based on her facing the right. We're keeping the vantage point in that same plane though and changing her facing. That's typically something we want to avoid. I think re-doing panel one with her walking towards us to keep the vantage "neutral" would help.. but that's just my opinion
The character in the center also changes costume by removing their hat.. you might want to alter the third panel to have this character placing their hat on the chair so the change happens in panel.
I'll reach out to a few people on the pacing and let you know what I hear.
