title: How could I render a Three.js scene with lighting and shading like this (attached)?
body: <p>I've always found lighting and shading to be the most difficult part of WebGL / Three.js to get right – I feel like I'm making it up.</p>
  
  <p>What combination of lighting and shading do you think I would need to achieve a similar look and feel to the following image? It's so soft and yet well-defined, whereas my attempts always come out harsh and haphazard.</p>
