My brother-in-law and my sister took some great pictures during their holiday in St. Ives this year. Two small, wriggly children, their soon-to-be-exhausted parents and an expanse of sand provided plenty of fantastic reference material to choose from.
My nephew, Alex, is three. His first venture into construction and empire-building with a bright yellow bucket did not go unnoticed as I pawed through the shots.
My technique breaks lots of rules. But it does allow me to operate within my own comfort zone and I like it that way. I print two versions: one full-colour and one black and white. The latter helps me judge tonal values and I also grid it out to help me draw it onto the wood panel which I also grid to scale (the reference image is slightly larger than the panel). The grid method is as old as they come, but is brilliant to help keep everything where it needs to be when you're drawing it out. Here's the drawing down on the panel (with the majority of grid lines removed from the panel) along with the two reference images:

When painting, I kept the background really simple because I wanted the focus to remain on Alex and to keep a strong sense of light and shadow. I also removed the spade and the bucket handle, as when I originally drew them in they pulled the composition down a little too much. So, ladies and gentlemen, meet my nephew:
