St. Thomas Panoramic

Or at least I think thats where I took these shots... Anyway, this was harder to do than I thought it would be, and it came out a bit crappy. You can see where I just plain gave up... But I spent too much time on this thing just to scrap it.

If anyone can tell me a good way to clear up some of those seams, that would be great... *is new to panoramics*

--EDIT--
I have resubmited the image. Thanks to *hal9k's suggestion of using Photovista, I now have a near flawless panoramic image Thanks man.
