Thinking about color

Working out an earthy color palette to recreate my Cidery watercolor sketch on a nicer piece of watercolor paper. I love the beautiful shade of Cobalt Blue and the granulation in the Green Apatite Genuine and English Red Earth. I like to have Jane's Grey for fine dark shadows as well, but I feel as though something is missing. Perhaps a bright yellow green or pinky red to create some apples in the orchards. What do you think?
