Insert a ready background or craft ?

I'm working in a 2D game. I can't decide between inserting a ready photoshopped background to my 2D game or to craft one !

is it a good practice to insert a 1024 by 512 slices then matching them instead of building the scene peice by peice inside unity ?


any ideas ? Please help.

 

I'm guessing you're referring to a scrolling background-- a static one can just be a large image applied to the skybox in Unity.

If it's made up of individual trees, boulders, hills, buildings, etc., I'd put it together as individual objects in Unity. If it's a continuous image of some sort that can't really be separated but still has a lot of unique features, tiling it is a fine way to go.
