I don't find the sky offensive in this image as there is very little of it peeking through the trees... the trees make up most of the setting. The white break in the trees actually makes a nice area for separation on the child's head. The white is also the brightest spot on the image, drawing the viewer quickly to the figures gaze. Nice bit of pentagon bokeh going on in the background. The lighting is a little flat on the face, but there is a nice highlight in the hair to produce some volume. A nice sharp image well separated from the background with control over the OOF area. He's also looking left (angled left) in the direction of the unused space. IMO, with a horizontal composition, I like the placement of the figure.
