Results not too impressive

This is my first attempt with CleVR stitch and I am not at all impressed. I tried to stitch 5 images of the Enola Gay bomber aircraft taken in a Museum and the results were horrendous. On the first attempt, it attached the left wing tip to the front fuselage and basically ignored everything in between. I tried again to see if it could handle just two images and again the results were unsatisfactory. I have attached the attempt I made to stitch just two images. I had better luck with a program called Autostitch.
