This is a step in the correct direction for uploading your photos as a photosynth, friend.
Your previous attempts are really shot more like single panoramas and should be uploaded to Photosynth.net as panoramas stitched with Microsoft ICE http://bit.ly/microsoftice
or Adobe Photoshop http://bit.ly/microsoftice
instead of uploaded as photosynths - which does not make a good panorama or a good photosynth.
Panoramas are good for providing the view from one single camera position. (Panoramas attempt to completely fuse and blend the photos taken from one point of view.)
Photosynths are good for allowing the viewer to spatially transition between many different camera positions. The nearest camera positions which observe the same objects must not be taken from extremely different angles or distances, however. (Photosynths show the beginning of the photos being combined in 3D through their point clouds.)
