Stempel's detailed drawings, created entirely by hand with a pen and compass, are strongly aesthetically influenced by the landscape of southern Germany, where he grew up. The rock formations, shadows of the trees, the stones rounded by the river on the riverbanks are deeply rooted in the artist's memories and inspirations.

Stempel also takes inspiration from man-made objects in the city where he now lives; the structure and transparency of fabrics such as silk or everyday textures such as reflections from water or scaffolding tarpaulins flow into his work.

The work’s themes and titles are deeply personal, coming from the thoughts, feelings and situations in which his works are created. Every drawing has its own personal story.
