I would have to take another look to be tell witch ones are, but i think generally is not a big problem, only when theres a lot of dialogue in the page that starts to feel crowded.
a way to fix that woul be either make the words smaller or put less speach bubles per page.
if you want to prioritizes consistence with your previous pages, i think the second option would be the best but if you want to keep the amount of words the same them the first one would be the best. or try to find a mid term.
upon another look i think the best size for a speech buble would be the one from the (its nothing) and (you're lovely) at the last page you published, try to see what font size would be possible to fit in a similar space, but also while also still be readable.
the font size from(oh yeah i remember) seems to be a good fit. i can read it and dosent take to much space.
