This probably applies more to the landscape architects out there. The wavy, tense lines you’ve sketched over an aerial probably do more to make the paper look like a piece of graphic design than they actually enliven the space you’re trying to create.
Always keep in mind that your designs are not for another design professional, they are for the public. What looks great in that 40-scale plan of yours doesn’t mean diddly if a parent corralling a screaming child or a mobility-challenged senior can’t put the pieces together on the ground.
I’m all for using details and relationships to create depth within our designs, but lets not blind ourselves by trying to make our plans look like modern art at the expense of the user or the site.
