This is better than you usually do but as Jack said the mod lacks finetuning and looks incredibly rushed.
Colors look alright but I feel like the colorvariation goes from nonexistant as a whole to severe at the stairs part. This probably stems from your tendation to copy/paste objects a lot more than necessary. Placing several objects with no variation in color/size/positioning/angles makes the mod incredibly bland and uninteresting to both look at and play.
It's a pretty good mod and I'd say it's definitely worth trying out but one thing that bothers me immensly is how NONE of the objects have been given angle values. Literally all of the visible objects have the base angle value. Again, this makes the mod bland and uninteresting
In most of my mods I try to make every single object unique in some way and spending those extra few seconds tweaking size/color/rotation for every object makes a huge difference
Keep improving :v
