Colours: Lemon yellow, cobalt blue, Sap green, Permanent red (cadmium red - a bright red)

I wanted this to look Japanese with one sweeping branch.

Sketch out the branch, the crabapples are on long stalks (like cherries) which are very pale so you need a dark leaf behind them otherwise the pale stalks will not be visible.

This is just to give an idea   Sketch the branch and wet the sky with clean water. Paint in blue, making sure that the blue stops before getting to the branch. Watch the edges as they dry, you don't want hard edges   Paint in leaves with mixtures of lemon, blue and green. Allow the paint to mix on the paper. Do not paint the outline of the leaf and then fill in the centre. Make leaves different shapes, sizes and colours
Start painting the crab apples using red and blue. Dampen the whole apple with clean water (they are round not grape shape). The paper should be damp not wet. Then paint in bright red leaving the white highlight. You need to judge exactly when to paint - too wet and there will not be a highlight too dry and there will be a strong edge. Then add blue for the shadows
