There is significant motion Blue due to Gondola movement. Plus there is lens blur due to distance and a need to crop a shakily hand held shot.
IMO, my friend captured the scene much better with her Supper Zoom Bridge camera. She could zoom in close. Plus she didn't have to wave a long lens and heavy camera body around on the moving Sky Safari. There is much to say about Bridge cameras in certain shooting situations.

Although not at all a "good" photo & what I consider a "throw away shot", I have included this image in the gallery because it is an example of what can be seen from the Sky Safari.
