Create a grayscale drawing featuring a rose and an hourglass combined in a unique and artistic manner. The rose should be highly detailed, with intricate shading to depict the texture of the petals and leaves. The hourglass should be elegant, with finely rendered glass and sand. Integrate the two elements in a creative way: perhaps the stem of the rose wraps around the hourglass, or the hourglass is nestled within the rose itself. The sand inside the hourglass could be depicted as falling onto the rose, creating a surreal effect. Play with shadows and highlights to add depth and contrast, ensuring the drawing captures a sense of timelessness and delicate beauty. The background should be simple and subtle, allowing the focus to remain on the rose and hourglass.
