1. Is this too much text to squeeze into six panels? In the grand scheme of things, how bad is it to cram too much text into a comic? In trying to adjust the text/picture ratio, do you find it's better to add more panels or to take out lines of dialogue?
The text is dense... there is a lot of it. Why are you creating a self-imposed six-panel limitation? I think there is another problem that you didn't put forth... the typography. You have two extremely different type designs, not only in look and feel but in historic development as well. I understand that you may be trying to introduce seperate modes of perception by mixing (juxtaposing) mechanical type and hand-lettered type, but these to are so extremely opposite that I find it hard to read let alone look at. The serif type is so dense... the hand-created type is so sparse (and if you're going for hand-lettered, why not actually hand-letter instead of a pseudo?)... I find them both tough to read (especially the Roman style face which has it's own rules for line-length, kerning, and leading for maximum legibility). Historically, the Roman-based serif type is from the late 19th century... does it belong to a strip set in 2018? Which leads to this crit, "If type is so important to this strip, couldn't you find two faces that interact better?"
As far as adding panels or editing (removing) text, I would answer... "Yes" to both.
Please do not take offense at this crit, it was offered honestly, and is subjective. Maybe someone else is not having the same problems with the typography.
