my 1st panorama

Hi everyone,
I have finally managed to produce my first panorama shot.
It is comprised of 8 portrait shots and displays the view from Bregenz's Pfaender mountain accross Austria's Vorarlberg towards the Austrian Alps.
I can see some flaws in it and am asking for some advice.
Should every shot be taken with the same aperture value and shutter speed ?
Does the white balance need to be set to a specific value ?
Thanks for your input, here it is:
Regards,
CD
