My little artist has discovered depth

It is a small step for a budding artist of four but it is still a major milestone. My granddaughter has discovered depth. Or should I say stumbled upon depth? She clearly liked the effect of the yellow heart sitting on top of the red shape. In fact, she liked the result so much that she overlapped a couple more shapes, creating a little row descending down the page.

I wonder if it is time to teach her about perspective lines?

I know she didn't intend it but I rather like the way the hearts morph into an almost butterfly shape by the time she reaches the top right corner of this piece. I say almost as my wife sees a dove as the final shape morphing out of a grouping of butterflies.

Whatever . . . in the end I like to leave abstract art abstract.
