Retouching ( cloning and blending) of a foreground

Looking to have the empty area in the lower right filled with flowers. The client is not happy with my attempts to correct the issue. This is an ASAP job. I am pass my deadline on my delivery. There are other files to pull flowers from. File are to large for loaded so they are in a dropbox folder. Image 7610 is the final. My layers and failed attempts are in there. https://www.dropbox.com/sh/4c5y794oq7pzntf/AABeMEZ9qdF1yvcbO-L_VnJ0a?dl=0
