The picture of the mosque is in equirectangular format and should
look much better with a 'normal' lens (rectilinear format).  I would
be tempted to align the verticals too:

The (rectilinear) picture of Strasbourg cathedral looks quite nice
to me.  You have cropped the bottom half of the output image, which
is why there is so much more distortion at the top than at the
bottom.

I would do one of these things:

- Align the verticals and accept that the picture is extremely
  distorted.

- Centre the output vertically so there is as much distortion at the
  top as at the bottom (ie. experiment with changing the 'pitch' for
  the anchor image).

- Centre the output vertically and convert to fisheye format.  Hugin
  doesn't output fisheye format so you need to use the gimp plugin.
