• Cassell’s work encompasses and generates complexity and surprise. All of her sculptural work shares a language of geometry and volume but each is intriguingly different
    – Elli Herring

  • Halima’s work demonstrates incredible dedication and energy; one thing is clear, she will be among the future pathfinders and leaders.
    – Alan Grieve, Chairman, The Jerwood Foundation

  • Her signature material is clay, which she moulds and carves with natural authority and no little dexterity. Her crisply cut and satisfying forms live on in the mind… She is a force of nature.
    – Andrew Lambirth, Art Critic - Spectator Magazine

  • The work is of a high standard and creates an interesting contrast to the Da Vinci drawing. Can see the evolution of the process and the sculptures convey different ideas and theories. An excellent artist.
    – Jina

  • …Although Cassell is creating in different media – and respecting the unique characteristics of her material while doing so – she is also intent on discerning just how bronze, glass, marble and clay can ‘speak the same language
    – Ian Wilson

  • Her profound understanding of the geometric rules governing any given pattern, allow her to bend, or even break them.
    – Peter Randell-Page, Sculptor

  • I love this artist’s work. How she keeps her molten flowing themes through different media – stone, concrete, wood and even glass. Long to touch them. What a unique eye and hand she has. Wonderful.
    – Maureen Lepman

  • She was sketching constantly and continually sought to transpose her drawings into sculptural forms. The surface as well as the shapes emerged together in sculpture which often combined enormous complexity with simplicity and unity.
    – Helaine Blumenfeld OBE FRBS Dlitt

  • Cassell’s Work Is Subliminal in its originality, having no parallel in the sculptural or crafts genres, whose borders it crosses.
    – Jean Vacher, Collections Manger, Crafts Study Centre, Farnham

  • I find her work uplifting, I would never consider buying it solely as an investment
