Environments/Kits vs Props

Hi everyone,

I’m currently an environment artist working in the industry and was thinking about maybe creating some things on the side to sell on the marketplace. I was wondering what people find tend to sell better full environments/kits (The PolyPixel stuff for example) that give the buyer a lot more to play with sold at a higher rate or smaller asset packs (e.g. each fantasy barrels, sci-fi crates, etc) sold at a lower rate?

Cheers!
