From the interview
When HILL magazine asked what's actually happening in the painting, not the art critic's reading, but his own, Soyerov described a man carrying an elephant on his back, hidden so completely that it reads as something soft and rounded, like a sofa cushion. The blue comes from a personal reference: a set of ceramic chess pieces he made, where the elephant piece is blue. The title itself came from nowhere deeper than how the words sounded together: "soft" for the shape, and for the way the blue material melts and flows across his shoulders rather than sitting rigid; "skill" for the idea of training into strength.
Once the painting was shown, it kept collecting readings that outgrew his own. One visitor connected it to a folk tale she knew: a girl who carried a kid goat every day and grew strong at exactly the pace the goat grew heavy. He's said he likes that reading more than the one he started with. It's a variation on an old motif: the Greek wrestler Milo of Croton was said to have built his strength the same way, carrying a calf every day until it grew into a bull.
At the exhibition, the painting held some of the closest attention in the room, much of it visitors trying to work out exactly what the blue shape was.
