It still needs tweaking! I haven't had any ideas yet as to how to tackle the slow patch near the beginning. That is my next port of call. I am very much still open to suggestion for it as well. I have since filled out the rest of the track.
I am certain the end sequence needs a revisit. Its far too empty, more needs to be going on as the features hop into the distance. Perhaps more elements breaking away and coming back, reforming whilst on the move? I have yet to work it out. However, for a break of sorts, I may get into rigging the 3D models for now!
