Place a half-filled glass of water before you on the table. A real object will make it easier for you to grasp proportions and shading (you can also use a photo). In order to describe the glass more successfully, first draw a rectangle on the watercolour paper with Warm Gray II 271 in delicate strokes. In the box, draw the outline of the water glass in warm grey V 274. Draw ellipses for the top opening of the glass and the bottom. Enhance certain parts with warm grey V 274, helioblue-reddish 151 and light ultramarine 140, but not too strongly so that no unwanted lines remain when blending later.
