Painting a family at Southover Grange

I have drawn all the family and used the Grange gardens as the setting. At first, there is a muddle of lines, but as I drop in the first colours the buildings begin to appear.
The three sisters wear the same dress but in their individual colours. These colours are set, but I will leave the flexible colours until much nearer the end of the painting, and I can use a mix of colours to balance the picture as a whole.
