I felt it needed more depth so I mixed ultramarine and brown ochre to make a grey-blue and laid a broken wash behind the leaves on a diagonal line as I wanted to keep some feeling of open space in part of it.
I dropped some purple into the foreground to bring it forward.
The masking was removed, then I painted the fruits. I gave the apples some red tones as they looked isolated. I sprayed some areas lightly with water so some colour bled into the surroundings.
The final job is to put in fine details like the stems and the ends of the berries. I also added some darker details to some leaves. I could probably have continued with details - but this is a sketch and I didn`t want it to lose its freshness. Now why don`t you have a go at your own version?
