I had a right job getting a photo with true colours, always problematic when taking pastel paintings. The sky is a bit too blue, and orange a bit more orange, and the sand a little dull, otherwise perfect! I've work some texture and tone into the beach, the started on the boys. The strong sunlight is casting hard shadows, so I'm finding it hard to keep the boys poses looking natural, not too graphic. I'm using eye-catching light illuminated colours so that you eye goes to them first then the sea in the distance. They've got a long run to the sea and the two in front are sprinting off to get to it, their elder brother looking on, pondering whether to follow!
