Though this painting seems to be moving quite quickly, it still has many subtle tonal details to be added to create the texture of the petals. I mix the colours that I am using for the painting to create the shadow colours; for example, a little red and green added together can be made to have a warm (red) or cool (yellowish green) shadow tone. The deep coloured throat of the flower provides great contrast to the sunlight on the petals. I cannot afford to take too much longer with the centre, as the masking fluid that I applied will be difficult to remove if left too long on the paper.
