Walmsley's style of writing ranges from the naturalistic to the poetic and, at times, the absurd. He moves easily between dramatic and comedic, and some of his "darkest" work is treated with a cutting sense of humour.
Walmsley's writing is characterized by its eclecticism, moving fluidly between serious and humorous, and even the darkest themes are infused with a sharp, ironic humor that adds complexity to his work.
