A glass hourglass with a gold sand inside sitting on a table

Pay special attention to the reflection and refraction of light on the glass surface, giving it a transparent and glossy appearance. Render the sand grains with precision, highlighting their individual shapes and the way they gracefully fall from one bulb to the other. Add shadows and highlights to create depth and dimension, making the hourglass look three-dimensional and lifelike. Include a visually appealing background that complements the hourglass without overpowering it, creating a sense of balance in the composition. Utilize a high-resolution reference image to ensure accuracy and authenticity in the rendering. Use a variety of shading techniques, such as cross-hatching, stippling, or blending, to achieve a realistic and textured look. Pay attention to the tiny details of the stand or base, giving it a polished and refined appearance. Experiment with different materials, such as graphite pencils, charcoal, or digital drawing tools, to find the most suitable medium for achieving realism.
