The fruit:

This is a similar exercise to the rose, for the same situation. The watercolour was opaque, and I decided to recover the drawing.

 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 the apples well, and I am also covering the background.

I used black to emphasize the apples, 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.
