1) Choose a place (real or imaginary) that is filled with lots of sensory images and action.
2) Describe it using as many images as you can.
3) Use as many similes and metaphors as you can.
4) Try to create a dominant mood, or atmosphere.
I am in paradise. The wind blows so calmly. The trees dance as the wind blows calmly by. The sun shines so bright that the sand burns my feet as they dig into it.
