Hi Susan. Always remember when painting foliage to leave a few gaps to see light/sky through. From the shadows, the sun is obviously behind the tree so the tree and cottage will appear much darker due to this and everywhere else full of light. Let a bit of sunshine actually shine through the branches and leaves, even show a few branches. Your painting is coming along just fine and just needs defined value, ie light and shade. Keep up the good work.
ps, watch which direction the light is coming from and paint the shadows accordingly. Hope this helps.
