Hand-painted clouds might look like one of these two cu's:



There are about 6-8 layers per cloud... A base layer of medium value, a shadow layer, a highlight layer, a glow layer, a scattered particle layer (little bits of cloud hangin about the main piece,) and a sharp edge highlight layer. The trick is creating a convincing mix of material that looks like a real sky... there's almost never a sky full of one type of cloud. When in doubt, use real pictures as reference.
