Break it up! Personally, I try to avoid giant chunks of dialogue when I can. The worst thing you can do is put a literal paragraph of text in a panel- because people aren’t going to want to read it. Most people tend to skim comics and when there’s a giant section of text, their eyes are like ‘nahhh’
Liiike this is an example of BADNESS:
But then if you break it up… it’s a lot easier to digest!
BUUUUUUUUUUT I’d recommend keeping the text per panel ratio as small as possible. Like, HALF of what’s pictured up there. Then move the other half to a second panel with some slight movement and BOOM it’s even EASIER for people to read and keeps it interesting! YEAHHH
I also try to keep the panel flow visually interesting, even when it’s just two ponies talking. Move around your imaginary camera- imagine your comic is a movie. You’d get bored if someone is delivering a monologue and the camera never cuts away from the same boring medium-close up forevahhh. Personally I try to never stay in the same “shot” for more than 3 panels. Keep it varied, yo! Keeps it interesting.
WOOOOOOOOO I HOPE THAT HELPS
