Keep it to a brief moment in time . Be there and savour the moment
personify objects Eg the door greeted them , the gate growled behind them
use pathetic fallacy. Eg the angry river suddenly eased and appear to be smiling at them through its shimmering glow
I concur with everything above and particularly the section
regarding using sensory perception
no more than three characters
First person is more subjective third person for more objectivity
be careful with tense . Itβs very easy to change tense. Eg as they entered the room he jumps .... ( should be jumped )
finally read what is said above . It mirrors what I was intending to say .
