I have this obby that ive been working on for past couple days im not sure what to put so any idea on what shold i add to make it look less plain and basic? The lobby was inspired by Plates of Fate: Mayhem and Cursed island.
Aside from the mountain/trees which others already suggested, I recommend more details on the pathway like rocks, signs, maybe even statues. Anything you could think really that would fit in the theme you are looking for.
I think that this is very bland and you should attempt to add some detail. Perhaps try adding some realistic grass (you can use this plugin by @XAXA), trees, bushes, etc.
