Paolo Rizzi from her personal catalogue: “…in F.Duso's watercolours a world of fellow travellers crowds all around. They are historical avant-gardistes, from Klee to Kandiskij, from Masson to Hartung. They are the background of a work full of intellectual and practical refinement.” And later… “her culture takes her to a perceptive abstract language and to a subtle allusiveness”. ….. “they are exquisite plots where an aerial fantasy sails made of vibrations that dissolve in the air”

Beatrice Rigobello Autizi from the above-mentioned catalogue “Evidenza e apparenza”: ….”works where the nuances interfere with each other, the colours interact and the plots are interlaced in a pictorial space where music becomes an essential element of perception. In F. Duso's paintings there is the elegance of Islamic decorative art and Klee's abstract charm but, above all there is the sense of a chromatic and poetic research of the mental image.”

O.Da Pos from her personal catalogue: “It should be emphasized that as in the other works of the author, the very white, transparent surfaces are easily visible as in “ruotando s'accentua”: this possibility had been denied by Wittgenstein, the philosopher, but foreseen by many perceptive historians”.
