Memoryoke, sorry to hijack your thread.
I'm glad you can find an upside to panorama stitching errors, but if you'd like to avoid (or at least minimize) these sorts of stitching error in the future, here are a few basic concepts:
Panorama stitching is 2D stitching:
When panorama stitching applications line up photos to form a sphere of photography, their first assumption is that all the photos have been taken from the same exact point in space.
What I mean is that if you are standing in the forest and you have a tree trunk close to you or an overhanging branch, if you lean back and forth the close tree trunk will line up with different parts of the background. Panorama stitchers don't understand this. When they try to line up all the different things seen in the photos, they will finally have to either choose the edge of the close tree or the trees behind it. Either one will leave rips in the stitching.
