Well, this was great fun. I am not considering a career switch to graphic layout, however, as my aesthetic is way antique. Uh, make that Classic.
Plus factors: basic layout provided, font sizes, colors. controllable experimentation, easy to edit.
Minus: I didn’t discover any, other than I could see lots of time spent “experimenting” (could a deadline be met?).
I can imagine the difference between my cover and those of 5th graders.
