堅定向前邁進女子的青銅雕塑

As an expert in fine art, particularly bronze sculpture, could you create a detailed description of a piece depicting a slender, muscular woman in her thirties, captured mid-stride to convey forward motion? The style should be raw, textured, and impressionistic, with visible chisel marks and subtle modeling defining her musculature and flowing tunic. Her facial expression should show determined gravity, eyes fixed on a distant point, lips slightly parted in effort. Include a light gray, rough-textured rectangular base, with warm, soft ambient lighting casting long shadows and highlighting the bronze surfaces, emphasizing the tactile qualities of the work.
