After working on the sky, mountains and woodland, I have now worked on the lake. This covers all the areas of the painting since the original base layer was put down.
For the water, I took some time to try and find a mix of paint that approximated the desired tone when it was applied over the existing base. Unfortunately I was unable to achieve the desired colour which was slightly pinker.
To create the water texture, I used spots or very short strokes in the foreground, and horizontal lines in the background. The current result is quite crude as it stands, but I hope to work on this further next week.
To introduce cohesion in the image, I also applied the same paint to the clouds and to the mountains because the lake is reflecting the light from those elements.
