I started with putting the boards on the right side of the shed door and then added more leaves to the climbing vine on the building.
From there I finished the large upright board leaning against the side of the shed.

I wasn't happy with the way the shed looked and I decided to extend the roof and length of the building.
Next I added another barrel on the left side of the boards leaning against the wall.
Perhaps I will add another window and put a door in the open space on the building and I will post this drawing at a later time once I have finished more of the building.
