Where's lion?

For this project we had to take one picture and erase parts of it. The first picture is the original, with three lions, but in the second one there is only one lion! I used the lasso tool and deleted it, photo shop filled in the rest. I had a hard time getting rid of the lion facing away from the camera because photoshop wanted to fill in another head from the main lion. What I had to do was delete small parts of the lion until the whole thing was deleted. The only thing that I don't like about it is that if you look really closely at where the lion facing away from the camera stops, it goes from fuzzy green to sharp ground.
