Thick paint, seen close
Vincent van Gogh
Paintings from the last five years of his life, all of them from the Met. Roses and irises, olive trees and cypresses, a pair of worn shoes, the people of Arles. Almost every one is built from short, loaded brushstrokes you can follow with your eye.
As a puzzle
The kindest pictures on this site to build. All that visible brushwork gives every piece its own direction and colour, so even a plain patch of wheat or sky tells you where it belongs. You can go high on the count here without it turning into work.
A good size here: 150–400 pieces.
