Finishing the rough paint
When I’m happy with the rough colour layer, I alpha-lock the sketch-layer by sliding the layer to the right. This locks the sketch, so I can only paint inside the existing paint in this layer. With my big Rull brush, I rough in colour in the sketch until I’m happy with the palette and feel of the image. The foundation for the rest of the painting is done, and it’s only taken me around 20 minutes.
