Reviewing Circle Games, Anna Scott in the New Welsh Review wrote, "Mazelis plays with the reader, introducing the unexpected by the back door. Fearlessly scrutinising the desires and impulses of her characters, segueing nightmarish fantasies into reality."^[7]

Reviewing Ritual, 1969, Rupert Dastur in The Short Story wrote, "Mazelis explores a dazzling range of ideas, geographies and times, often couched in the daily realities of women and children, the marginalised and the powerless, the scared, hopeless, and hapless ... Ritual, 1969 reveals the absolute mastery Mazelis has over the short form and this third collection is a superb display of a writer keenly attentive to the human mind, its motives and its mysteries."^[8]

While working for magazines in London in the 1980s Mazelis photographed writers such as P.D. James,^[9] Patricia Highsmith.^[10] and Kathy Acker,^[11][12] artists Paula Rego and Nan Goldin,^[13] and actors Miranda Richardson^[14] and Tilda Swinton,^[15] amongst others.^[16] Mazelis photographed John Stevens and Dudu Pukwana on a number of occasions, notably while they were recording the album, Radebe: They Shoot to Kill.^{[17][unreliable source]} Since returning to Wales she has photographed a number of Welsh artists and writers including Ed Thomas, Francesca Rhydderch, Lloyd Robson, Kevin Sinnott, David Hurn, Rachel Trezise, Richard Davies, Tristan Hughes, Rhian Elizabeth and musicians Richard Cowell (Rag Foundation) and Paul Battenbough.^{[citation needed]}
