(b) It it's easier to visualize in the stitching software. (i.e. 1 goes above 9, 2 and 10, 3, and 11, etc.)
(2) When you setting up the camera, try and get it as level as possible - it make a huge difference when stitching... I use a bubble level in the hot shoe ($5 bucks on e-bay).
(3) There is a difference in exposure between the Upper and Lower shots. (a) I couldn't see the difference in your EXIF data, but if you compare "P1380082.tiff" and "P1380100.tiff" there is a significant difference where they overlap.
(b) It looks more than just vignetting.
(c) It is also there between frames but not as bad (so it may be vignetting).
(d) Anyone else have any ideas? More overlap to reduce Vignetting?
This was the end result with some saturation added!
I didn't attach the full detail one owing to the significant difference in exposure (point 3). Made it hard to make the image workable.
Compare the output to this, which I did in less processing time (I am comparing the processing time not the picture) - It is incredibly important that your original setup is the best you can or it will take heaps of time in post processing, and you may never get the result you wanted - It's a learning exercise and I can't understate it's importance.

Thanks heaps for having a go, and for your great advice
next time I'll take each row starting from the left and make sure my tripod is very level.
