This is a similar exercise to the rose, for the same situation. The watercolour was opaque and I decided to recover the draw.
This is what we are going to paint
I emphasized the apples so that you can see the effect of water on the pastels
As you can see I covered well the apples and I am covering also the background
I used black to empathize the apples did the leaves, and the orange, I also did the space surface
This is the final result without a spaceline
At the final, you make an imaginary division line.
