Just in time for Halloween

About a month ago I was inspired to do a still life with a Fall theme when I was looking through the produce at the grocery store.  So I purchased a pumpkin and a couple of gourds.  That same evening I was flipping through a book of Dutch paintings and found a still life with a skull painted by Peter Claesz in 1630.  As I was arranging my composition for the still life I thought it would be cool to include the skull from the Peter Claesz painting to give it a bit of a Halloween theme.  So I could capture the cast shadows of the skull on the gourds I used a head of lettuce where I was going to add the skull.  Here is a photo of the arrangement, a sketch of the composition, and the final oil painting.
