We get used to a certain kind of colour of form or format, and it's acceptable. And to puncture that is sticking your neck out a bit. And then pretty soon, that's very acceptable.
At that point it certainly would be called abstract. That is to say, you had a model and there'd be one or two or three people there drawing the model but otherwise you had abstractions all around the room, even though the model was in front of you.
All my work keeps going like a pendulum; it seems to swing back to something I was involved with earlier, or it moves between horizontality and verticality, circularlity, or a composite of them. For me, I suppose, that change is the only constant.
