As the design calls for soft, flowing areas of paint, using acrylics rather than oils involves practice to avoid ugly *lap-lines* where the paint starts to dry before blending is finished.
Once I begin painting an area, taking into account the dryness of the air, I plan how much I can cover before the paint will become unworkable. Once it reaches this stage, I need to stop working it, let it dry before painting another layer.
The bamboo was to be painted as it would be hit by sprackly uneven light; I *oil in* ( using an acrylic glaze medium) a slippery layer over stalks that I have laid in with a base color; then I work quickly to soften the patches of different colors into it. Once this dries, I paint the more linear shadows and highlights with the aid of a mahl stick.
