my painting so far..

                      The rest of the blossoms have been painted the same way as the previous ones. I have faded out the flowers as they move towards the left, to stop the eye from going out of the picture. So that there is not an abrupt jump from detailed and high contrast area (1) to no-detail and less contrast area (3), there is a middle zone (2) where there is somewhat of a detail:

               For the branch, mix some new gamboge to your violet (shadow) mix to get a pale brown, lay in wet-on-wet and before this layer dries, add a shadow on the underside with a darker (i.e less-diluted) mix of the same color. As it starts to dry, you can add some knots and lines with a detail brush.
