I used a photograph taken in a park for the background (source 1), then cut the tree of the original picture and modified it with different tools to simulate the "arms"
From source 2 I cut the pigeons and put them in different positions... hope you like it!

I thank to zeanalacrimosa for the pic of the hands, and to katmystiry for the pic of the daisies, both artists from morguefile.
