Pastels provide the artist with the opportunity to develop the details of the piece of art towards the latter part of the work. Although it is wise to have a rough picture of the details earlier on, there is no necessity to develop them meticulously right from the start, instead, the artist must thoroughly dwell on the tones and colours of the piece of work at these initial stages. Colours must be used on the bigger shapes and refined as the right image takes shape. When such undertones of colours are completed, the minute details can be finished bringing value and depth to the work of art.
