Hsiao Ron Cheng, Vanessa Foley, and Keith Carter present new works that share a soft, delicate color palette and plenty of floral flourishes for their three-person show, "Tread Softly." The title of the show perfectly encapsulates the way in which these works ought to be viewed. They beckon a quiet contemplation to take in their many, muted details, ethereal figures, and folkloric motifs. "Tread Softly" opens April 30 at Antler Gallery in Portland.
