"Caduta di lago con scultura" shows Garau's focus on water.
"Garau sees an evocative, passionate and romantic language with touches of color that create dreamy water plays of celestial and blue lights and shadows that plunge into the black earth. The theme of water is loved by Garau, who has deeply studied the movements both natural and determined by human technology, dedicating several exhibitions to this topic. " (cit. P. Biotti, art critic)[4]
