The Struggle for "Voice"

My mother would say my painting is "kinda differnt." She would pronounce it just the way it's spelled here--differnt or maybe diffurnt. I don't know what my father would have said. Maybe just grunted. Both of them might well wonder how their son got on a path to find a new "voice," as we say in writing. I don't know what the word for "voice" is in painting. Maybe "style"? Dunno.
