Create very soft shadows in three.js?

Question

is it possible to create a very soft / very subtle shadow in three.js? like on this pic?

everything I managed to do so far is this:

My Lights:

hemisphereLight = new THREE.HemisphereLight(0xaaaaaa,0x000000, 0.9);
ambientLight = new THREE.AmbientLight(0xdc8874, 0.5);
shadowLight = new THREE.DirectionalLight(0xffffff, 1);
shadowLight.position.set(5, 20, -5);
shadowLight.castShadow = true;
shadowLight.shadowCameraVisible = true;
shadowLight.shadowDarkness = 0.5;
shadowLight.shadow.camera.left = -500;
shadowLight.shadow.camera.right = 500;
shadowLight.shadow.camera.top = 500;
shadowLight.shadow.camera.bottom = -500;
shadowLight.shadow.camera.near = 1;
shadowLight.shadow.camera.far = 1000;
shadowLight.shadowCameraVisible = true;
shadowLight.shadow.mapSize.width = 4096; // default is 512
shadowLight.shadow.mapSize.height = 4096; // default is 512

and render:

renderer.shadowMapEnabled = true;
renderer.shadowMapSoft = true;
renderer.shadowMapType = THREE.PCFSoftShadowMap;

thanks you

You can soften shadows by setting radius like this:

var light = new THREE.PointLight(0xffffff, 0.2);
light.castShadow = true;
light.shadow.radius = 8;
