I have added some highlights to the twigs and started to put a little of the flower colour in the top right. These areas are small and are set against the sky. To make then feel more natural, after painting them, I blur the edges slightly with clean water. When left as 'hard edge' shapes they tend to look 'stuck on' which is not the effect I want. Even when the painting is completed I do this to any areas that I feel need it.
