Bas relief pieces are created by sculpting an original and then casting the finished pattern in plaster, Jesmonite or cold pour bronze. Jesmonite is a versatile, non-solvent based material which can take exceptional detail. The resulting casts are heavy, matt and cool, akin to stone or plaster. 

Tobias approaches each sculpture with precise observation and an acute interest in the minutiae of the subject matter. Even when working on large scale projects, he ensures every area of the piece has been delicately articulated.
