Create a dynamic Sumi-e painting featuring a tiger crouching amidst dense bamboo, ready to leap, with a focus on creating tension and focus through varying brushstrokes. The tiger is rendered with strong, sweeping strokes, showcasing its muscular form, intense eyes, and crouching stance, while the bamboo is created with softer strokes, adding a sense of depth and environment. The composition is focused on the tiger in the foreground, with the dense bamboo surrounding it, creating a sense of enclosure and tension. Use a thick, firm brush for the tiger and a thin, flexible brush for the bamboo to achieve the desired textures and effects. Keywords: Sumi-e painting, tiger, bamboo, dynamic, tension, focus.
