Semper’s drawings are executed to imitate woodcut prints, embody a personal, invented mythology after the fashion of William Blake in the early nineteenth century; the symbolists, surrealists and decadents; and up to and including British artist Patrick Woodroffe’s Mythopoeikon (1976) and The Pentateuch of the Cosmogony (1979) and the forerunner of Vienna School of Fantastic Realism, the influential visionary painter, Ernst Fuchs. Semper’s woodblock style has some affinities with Albretch Durer’s, but is quite unique, drawing heavily on both the Roman Catholic and supernatural folk traditions of the Philippines, quantum mechanics, alchemy, world mythology, classical art, occult, art nouveau, and the gamut of erotic drawing from Japanese Ukiyo-E to Aubrey Beardsley.

In 2009 he worked with Mexican artist Hector Pineda to co-edit the book “Imagine the Imagination – new visions of Surrealism” (ISBN ). He was also included in the publication.
