I posted a picture of this scene before, but in that used a wide range of watercolour colours. In this, I was keeping it far stricter to explore the key areas. It is a method I use to really get deeper into a picture. By removing different parts, such as colour, it is possible to focus on one aspect to see where you are going right or wrong. After the focus, it is easy to go back and bring in the missing element. The key is to not get too stale when re-drawing or painting the same scene.
