Washington crossing the Delaware

Needs explaining,:   With no school in sight, this family is trying creative learning,.   :-). A challenge was made by the uncle to Kirsten  and the girls ( but let’s face it, mostly it’s Kirsten game) to recreate this 1851 painting ( of revolutionary 1776) by Emmanuel Leutze, ...with the huge number of play mobile people they have,    Brilliant, I think.   But what about that Norwegian flag.. ? 
More challenges ahead,  Le Gran jatte?  The Nightwatch?
