Forth bridges panorama (350D)

Here is my attempt to catch a night panorama of the Forth road and rails bridges in Edinburgh, Scotland. 350D, Sigma 17-70, 30" f/13 ISO 400.

Any comments welcome, especially if anyone has a good idea on how to correct the curvature of the image along it length (i.e. the ends pointing slightly downwards).

Thanks for looking!
