Too many words can overwhelm the art leaving you with a "talking head" comic like CATHY. My favorite comic ever was PEANUTS and my favorite comic in today's papers is JAMES. Both are verbal comics where the art supports the writing, but look how clean and uncluttered the strips look. Neither wastes space with too many words or too much detail in the art.
I try to do that with TELLY. I try to find the fewest words to tell the story. One of the questions I have about TELLY is do I rely too heavily on the artist. Today's (6/4) is about as wordy as I get. Is the dialog in panel 3 too much?
Johnny, is your comic a panel or a strip? IMO, panels, such as the wimp-men here does, can get away with too many words since it can't show movement as well as a strip.
What do you all think of panels with more than one punch line? THAT'S JAKE,for example, often tries to cram too much into his panels, distracting from the main gag.
