At 0:24 you collided with the centre road thing, don't do that.
A lot of your turns were fairly smooth in the first section, however, there were a few bad ones.
The onfoot section through the 'park' was fairly smooth except for hitting that wall.
The one onfoot section just before the truct (with the stairwell and robots!) wasn't that good. You collided with the wall of one of the "pillars" slowing you down a fair bit.
And then the GUN truck actually hit you.
Get rid of all these things, and you should shave off maybe 8-12 seconds
Other than that, fairly good run.
