Well, my DD is also like an "anti-aspie" who also has a very large amount of commonality with ASD people, too.
So I know what you mean. I think.
I definitely have seen "start with an oval" go into very good places that use children's imaginative skills as artists. "What could your oval be?" and "Can you picture (what the child asked to draw) in your oval? What else do you think that it needs?"
I've also seen it go in bad places... "No, that's really more of a squashed egg that looks like a rectangle..." or "Um, well, that's a great lake, but we are drawing a flying saucer with our ovals today..."
It just sort of depends on the circumstances.
