The first step was to create leaves meshes from photos. I was quickly done thanks to images and alpha channel quality.

After creating a bunch of leaves, I started modeling the birdhouse, helped with some reference pictures I found on the net. Planks materials were done by mixing several layers of wood textures.

The next step was to choose an interesting angle of view, then to place the leaves to create the composition. The out of focus background is a mix of several already blurred colors.
