1. never use a landscape layout, gah. it looks like a “portfolio” not a well designed print document.. why do you think magazines are portait.. it look better.. easier to handle.
2. dump the scales. it doesnt matter. they look clunky and ugly, seriously who will notice that its 20 scale or 100 scale..
3. stop worrying about all these presumed rules. just do what makes your work look the best.
4. make something that you are proud of, not in papyrus!!!!
