Use basic shapes to sketch the wine bottle, glass, and cork.
Develop the shapes, erasing unneeded lines as you go. Suggest the liquid in both glasses and block in the wine label.
Start shading, leaving white areas in places to suggest reflective surfaces. Add cast shadows, a tear in the foil at the top of the bottle, and a piece of foil attached to the cork. Texture the cork with small dots.
Darken all the elements, taking care to leave the highlights white.
