Hey Bloxburg Team, suggesting a weather/lighting update realistic atmospheric ambient lighting. Posted about this in tips-and-tricks on official Discord (user: wrenz428) with pics so if u have time please check it out for ref.
Suggestions:

Sun latitude at 60 in Studio instead of 24 less forced, more realistic shadows.
Sunset/sunrise are too dark/plain brighten slightly via Tween/Heartbeat at value 2
OutdoorAmbient can be bluish at sunrise, purplish at sunset (base 99,90,106). ColorShift: 255,170,0.
Haze: 2.2, color 202,221,255 at sunset.
Glare: 0.9, neutral 162,162,162, localized near sun (not spread across sky); alt color 150,162,88.
Atmosphere density: 0.2 normal, 0.3+ for morning-breeze look.
EnvironmentDiffuseScale: 0.5
SunRays intensity can be 0.07, spread .3.
Tween timing for sunset colors can be from 3pm and Sun vanishes at 6pm leaving flat dark sky keep haze/glare active, tweening down 6–7:30pm for lingering afterglow. Sunrise: tween 4:30–6am, full daylight by 6–9am.
Variety: hazy-white or blue-green (cloud-diffused) sunsets variations can be red sun/green sky or red moon for Halloween as well.
Skybox can be new default blue skybox more natural than current turquoise one.
Clouds/terrain: decal clouds on parts instead of Roblox clouds for better performance triangular terrain is also cheap. but if ur Keeping Roblox clouds utilize them for rain/cloudy weather (dense) add separate cloudy weather type.
Day rain can be greyish clouds, haze darker than clouds for dark edges, brightness 0, dark neutral ambient, cloud density 0.1/cover 1, diffuse scale 0.1, streetlights on. Can be darker at night.
Thunder flicker script via RemoteEvent/LocalScript, randomized brightness per flicker, gradual buildup clouds thicken > distant thunder > light rain > intensify > repeat backwards
Mix roblox + moving decal clouds during rain; cap rain just below snowy mountain peak so clouds appear to sit below it.

Shouldn't be CPU-heavy, mostly value tweaks. Hope you guys see this.
