A watercolour wash of sap green has been applied to the most prominent leaves. Sunlit green has also been used on many of the background leaves to add a little warmth to the painting.
At the top right hand side of the painting I lifted some of the paint (wetting areas and dabbing it with tissues) for the lighter veins. Next I deepened areas with midnight green.
I am using a no. 4 brush with yellow ochre for the stems, darkening areas with a mix of Vandyke brown. White gouache has been added for highlights on some of the leaves.
