Fersen is an accomplished poet who regularly plays with language, using puns, rich rhymes, symbols and images taken from the realms of plants (vegetables and fruits) and animals (birds and various beasts) to tell stories or original fables, to recreate moments from daily life, impressions and sentiments, and also the dreams of ordinary people and their failings and faults.
Fersen's work uses vivid imagery and symbolism to explore the lives of ordinary people, their dreams, and their flaws. He employs a rich vocabulary and creative language techniques to create engaging narratives and evoke emotional responses in his readers.
