Storytelling sketches

I'm working on sketches that are more "storytelling". The first two show a child playing a musical instrument and attracting a bird in the process. I thought the piccolo player was too stiff. The flute player is more relaxed. I'd like to do a final of her with a music stand in front and a garden behind her.

The bottom sketch is a boy building with toothpicks and peas, or marshmallows being pestered by his siblings. Title is "The Problem with Siblings". The baby, hidden by the sculpture is reaching for it. Totally lost in the sketch. I need to find a solution to this problem. Hum......any suggestions?
