Ok, I used the clone tool and paint brush. No mask no selection no layers. I am kind of old school when it come to PP. I do use CS6. What I did was go to the larger size cloning tool and worked on the orange tree. Then I set it on the bamboo rail along the walk and extend that along the walk. Setting the source on one of the support brackets and placed it on the start point on the rail near her and extend that. I then went to the Light colored trees and cloned them over the people that were standing there and down to where the walk way should have been. Know all that was left was about one half of you female friend. I then selected the paint brush and click on the color block to get a brown color. Setting the pressure to about 80 I spayed the women away as a walk way. I added a lighter brown to break up the contrast of the walk way. I didn't try to make this a keep sake being that it for infrastructural use only and you are to complete you photo to your liking.

It would be nice if you did your complected drawing so we can see what you did and maybe give you a few pointer.
