Thanks Vince for the comments.
It is a whole lot like a missing tooth and with me there is no way to ignore it. The cutomer paid for a quality pano and that is what I intend to provide (best to my abilities that is)
As far as leather looking washed out, it may be due to the photomatix and merging the 3 photos. I used the details enhancer and tried to produce an image that did not look HDRish or I guess I should say IDRish.
I posted on another forum as well to see if it was a defect in the camera. It appears to be the shooter. I need a slower shutter speed for the room itself then use that with the one decent underexposed shot for the windows. I am just not sure how it is going to affect my blending ?

Still going to update my camera though I really want the 5D but have an EF-S 17-85 IS that I will no longer be able to use. Should I go with the 40D I would still be able to use this lens. Unless someone here is interested in buying a EF-S 17-85 IS lens that has not hardly been used?
