"Composition in Shape and Shade"

I have the windows open and the birds are giddy.  We should all be giddy after the winter we had.  I know we're lucky to live in the mid-Atlantic, but still, compared to most years...

I'm posting my new painting "Composition in Shape and Shade." (Acrylic on canvas, 36 x 48"). I'd love some feedback.  For instance, my mom wants to know the little boy's name, what he's looking at, what he's reaching for.  I tell her it's not my intention to tell those things.  I'm just asking the questions!

I hope my (awkward?) title tells you that the subject matter is not important for me but that I'm exploring light, shade and shadow.  This painting is from a photograph I took on Spring Maid's pier in Myrtle Beach a couple of years ago.  I was fascinated by the light patterns on that November morning.
