Final texture tweaks
To add steam to the tea and solar flare-like textures to the light, I create a new layer, change the Composite Method to Screen and paint the steam using the Candle Smoke 2 particle brush. I duplicate the layer and add blur to the bottom copy, then combine them. I create three layers and set the Composite Method to Screen. On the bottom layer I use the Casting the Net brush to add texture over the light; on the second, I use Atomic Particle to create the spiral. On the third, I use Crack Thing to add smaller textures close to the light.
