the spring one is pretty spot on. An easy way to do these is to take personal experinces and apply them. Lets take your busy street one and work on it. Sensory language applies to your five senses. so on a busy street, what would you hear? The sound of vehicles buzzing by on crunchy asphalt roads, the sight of tall buildings and busy people walking to and from places. The smell of savory cooked hotdogs and candied asorted nuts, The murmur of people as they walk down the strert. The taste of street food, whatever it may be mixed with subtle hints of dust. the feeling of heat on the skin or maybe cold if its winter. These are just a couple of examples.
