Beach fun time

this illustration is of a dad who's taken his two young children to the beach on a sunny day. The dad is sleeping (or as he would say "just resting his eyes") in his deck chair as the children play. The daughter has been busy running about playing in the sea and collecting shell to show off to dad. The son is having fun in the sand and sneakily burying dad's feet in the sand when he's meant to be building a sandcastle. 

I loved building sandcastles as a kid, we'd make hugh castles that had big moats filled with water and rivers leading all the way to the sea.
