Something I noticed with titles of comics on Tapastic is that I've seen a lot of slice of life comics with random food names as the title? Like I can't remember off the top of my head (nor would I want to single anyone out), but things like "Cotton Candy Waffles" or like "Bubblegum Cookie Dough"--like just random sweet food names that go together in a weird way. This always was offputting to me because generally when I would look over the comic, the title didn't really seem to have any meaning whatsoever to the actual comic? Maybe sometimes having an irrelevant title will work for some stories, but I feel like it feels kind of immature or like "randumb" humor type stuff and its offputting (in my opinion, of course, not as a strict rule!)
I've personally always been a fan of titles that have are from an emotionally striking part in the story, like a key word or a phrase used at the very end of the series or during the highest peak of the climax. For example, I have a side story called "Another Life," in which one of the major lines is "we'll meet again in another life" said towards the end at the height of the climax--this kind of thing has always sent shivers down my spine personally when done in other media! This, of course, takes a lot of planning ahead and knowing exactly what direction you're going with your story, but can be a very powerful tool on a narrative level as well as a titling level.
