After her performance in Nancy after the Master Class with Jose Cura in 2007 the critic wrote: "Very deserving, a young soprano moves on the stage gracefully but without affectation… We are struck at once by the consistency of her tone, luxuriously copper-colored, so to speak, rich and full but very docile, effortless. We learn with astonishment from the program that she also sings roles requiring great vocal agility, like Gilda (Rigoletto) and Norina (Don Pasquale)..."
