Create an acrylic painting of a fantasy cactus character with notorious brushstrokes. The cactus is green, little spiky and a humanoid shape. It has wide, round white eyes and a small open mouth, giving it an expressive, startled and sad look. Its arms are raised as if waving, with one arm higher than the other. The background is simple and neutral, with soft shades of light beige or sandy tones to evoke a desert setting. The acrylic painting should emphasize texture, with thick brushstrokes on the cactus and a natural, slightly surreal atmosphere.
