Fresnaya was a soft combination of Cubism and Fauvism; I say soft, because the Fauvist aspects were rather lightly applied. But perhaps "soft" can be carried over to the overall character of his works, which, even though they contained harsh lines representing naturally smooth objects, still somehow retained a very gentle overall character. And ultimately Fresnaya himself was a soft character, whose health declined rapidly after his service in WWI, culminating in a very untimely death.
