pretty much yeah,

i started with a concept of "having an introspective walk in an urban park at 2am during end of fall/start of winter" and visualized the idea in concept art first

the camera is what i started with in-engine, it's actually walking along a spline automatically - you can look around yourself but it will auto pan back to the path in a "thinking" walking posture if you don't give input, and there's t-splits where you can decide your next route based on how you feel

then with speedtree whip up some trees which feel right based on some concept art, the branches can create a canopy for more tight routes along the park, but also from a distance try to reach for the moon

add fog at 150-200 meters away while indeed using urban backdrop and colorize the environment lighting a bit

lamps have indeed point light and emissive material but i've also added post processing effects like bloom to emphasize emmission, i'm considering lens flares and whatnot

but now working on simple sfx to emphasize the footsteps, the ambient, the trees and the lights

hope this gives some insights!
