I really like the sound of your edit without seeing it yet.
Have a dig through this thread particularly about structure of the opening and the big chunk of still further deleted material.

If you are planning a version 2 then there is scope to go further with some structural issues and visual effects.
But if you feel done with it and happy then no problem but I think there is still more to unlock about the film I wont list them all out but let me know if you feel like doing more.
