Create a Design

I want a landscape/garden design with details such is what in the picture attached but with different idea. In other word, I am looking for new ideas especially for the pond and the stream place, shape, and sizes ...etc. The existed things in the garden are: the house at the left bottom corner, the Well, the Gazebo, walking steps from the house to the Gazebo, and finally the trees along the fence. the rest is just in the drawing.
