I guess this is another of your experiments. I would recommend that you to slow down the speed of the pans. Try toning down the level of colour work a little or it will begin to look more cartoon like than real video, unless that is the look your going for.

Agree with Pan comment . . . I prefer to see simple fade transitions if it's a long pan. ie The Start and Finish. Somehow our brains think we've seen the whole vista, even when we havent.
To improve the frame-rate you might try a really slow pan,
then speed it up in Edit - that way the PC has plenty of data to work on.
Sliding at 0:50 looked much better than pans.... Some beautiful shots (eg 0:17)
