Bronzene Läuferstatue im vollen Schritt mit intensivem Blick nach vorn

You are an expert in art criticism and sculpture analysis. Based on this precise description, please interpret the stylistic and expressive choices of this bronze sculpture: an athletic man in his thirties, caught mid-stride, with a raw, textured impressionist finish showing visible chisel marks and subtle modeling. His gaze is fixed forward, lips parted in effort, draped in a flowing tunic. Include how the warm diffuse lighting, elongated shadows, and rough gray base contribute to the tactile and dynamic narrative.
