Panorama 2 - Stitching Nightmare

After shooting the images, I have realised how difficult this will be to stitch. 

Firstly, obvious perspective shift.  This occurred as the counter is so close to the camera, and as the camera pans it creates a shift in perspective. If the counter was further away, this would not occur so obviously. 

Colour shift and perspective. This occurred as, once again, the object was very close to the camera lens, creating the shift in perspective. The colour shift was from the window being above this, making the camera exposure change and creating a darker picture. This is after I have used levels and curves to recreate the best colour possible. 

A pretty awful merging of a straight line, once again because of the object being so close to the camera. The tiles in the reflection are also distorted, aswell as a colour shift.

Vertical / Horizontal lines merging and colour shift. Another very difficult thing to achieve.

These images are after I have tried my best to merge the image, but in some cases a smooth stitch is seemingly impossible.
