Going OK But It Is Getting Complicated

I have been working on my images but the stitching is starting to very fiddly and complicated. This is because where i change the angel of the camera on the tripod the shape of objects changes as i move round the location. this means that i am going to have to use tools such as worp and distort but sometimes this still cause me some problems. This is because when i use these tools sometimes it changes the shape of and object the other side of the image.
