Has a nice feeling, atmosphere true.
Also cool buildings and easter egg in lake hehe. IMO too many dynamics (just the look of them in a row).

I'm sure you would win the 1 hour max. track creating contest
Still, it's 3km and to be good quality it would need like 3h of editing (according to my basic rule).
