This composition, similar to the one below is basically a pyramid, one of the most simple and time honored compositional ideas - ever. Except this one is allowed to escape the picture plane creating a less formal feel to the entire still life. For the sake of variety a couple of the elements have changed. I got a little burned out on pears last spring and tho' I have never been as fond of painting apples I think there is much to be squeezed out - and that's not just juice.
I have noticed how, when confronted with familiar objects the tendency is to paint what we think we know, as opposed to really looking to see that thing as it really is. In this sketch the apple "breathes", while the one below looks like a shape that was cut out and pasted on.
