Had another go at the cocktail glass centred layout. This time using aquarelle water soluble pencil and an eraser. This is just another small thumbnail although I’m not unhappy with it. I added water in selected parts only to try and increase the contrast. Lack of contrast is always a failing of pencil drawings in my opinion. Still not contrasty enough to my eye. Eraser worked well to fade the areas that had light reflection. Pencil still not smooth enough to say water but I have tried to use the observed tone and distortion to suggest the glass.
