鋭い前方の視線で疾走するブロンズランナー像

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.
