This time I decided not to lay down the sky first, but to work on the foreground and background at the same time. I drew in the foliage, then filled in the gaps with sky. Then I filled in the gaps in the sky with more sky colours, then back to the foliage.
I completed the top half and took a break before tackling the bottom. That was when I decided to pick out the reds in the planting behind the fence. I went a bit wild with pinks and purples, but I'm happy with the contrast to the sky. That done, I needed to beef up the tree some more.
The muted greens and greys are still merging too much with the scruffy blues in the sky. Any ideas how to bring the tree forward from the sky? Anyone?
