I have added one of the main twigs, which was a concern when I included it into the composition, as it may 'cut' the composition diagonally. I decided that, once the flower shapes have been added, it would counteract this possibility somewhat. I have posted two photographs, taken a few seconds apart, taken with my ipad mini. The first, with a blue bias was taken using natural light only and the second with the addition of indoor LED lighting. The blue bias could be a result of the fact that the ipad may not have a skylight filter with the camera lens but, to be true, daylight is the best when painting to be able to see the true colour of what you are doing. If painting at night, I use a special craft incandescent bulb, which gives of a natural daylight.
