Brissund Small Planet

EDIT: I'm currently working on a new small planet picture, this time with a much better method, stay put for the new one which will include a guide of how to make one.

This is one of my first attempts at making a small planet - panorama with stereographic projection - from a 360 degree panorama from 67 images. Full view is recommended.

I used Hugin to stitch and blend the 67 images, mainly with it's automatic control point algorithm with just a few manual corrections.

I then used Photoshop CS3 to make a small planet with the Polar Coordinate-filter. The midpoint is taken from another image I took of the ground where the camera stood.

The result isn't all that great, there are lots of better small planet images out there, and ANY help of how I should change the process to get a better result is appreciated.
