Start by painting a heart and the petals of the two large flowers with liquid khaki paint (without adding water, using a fine brush).
To arrange the paint in the bottle precisely, it's best to pour a little paint into a bowl and pick it up (gel-like) with the fine brush.
Paint the outline of the large flower, the heart of the other, and the petals of the cut flower, in metallic color with good silver highlights.
Paint the heart of the large flower, the outline of the petals of the second large flower, and the outline of the cut flower, in pearly green.
Take up the khaki paint to highlight the outline of the cut flower.
