I see what you both mean, and honestly I've thought of it before doing myself too. But the setting here is a little specific. Even though it's basically cyberpunk (as in the design and the setting of the game), the level where this train is is a very filthy, dust-covered slum - the lowest kind of slum you can imagine, not the usual wow colorful slums with bright neon lights you often see on Google (think Brazil's favelas with traces of advanced technology). So the low saturation or RATHER the inclination towards gray is to express that everything is dusty and has been exposed to natural elements for a long time. Also, it's not an object on the same depth level as the character ;)

Thanks you both a lot for the feedback though!

I meant saturation, of course.

"What does it being "whateverpunk" have to do with anything here?"
Steampunk, cyberpunk asf tend to use special palettes with too bright or too low saturation. If it`s future cyberpunk, colours are usually saturated pretty much, and the contrast is quite high, too; if it`s sort of post-apocalyptic steampunk, the palette is often "dusty" - low saturation, low contrast. But in your piece saturation is waay too low. Imho, of course.

Edit

With the quick consideration that it's a destructible foreground sprite (same depthe level as a char)

snowpiercer!! :D

I really like the ruined version!

Do you mean contrast or saturation? The saturation is low yes but I don't think this has low contrast. What does it being "whateverpunk" have to do with anything here?

I think that the contrast is too low even for whateverpunk.
