Goal to become environment concept artist

[Fedodika]

Hmm, I like your start here in good perspective. Since you're placing this building thing, there isn't anything I'd change with that, it's just the background. It's very flat and like a few skill levels behind the building. Some good things you could try is adding diff shapes in the mountain ranges on the right side, and maybe adding some mountians or rocks on the left and show some depth with like rocks or mountains in the distance.

Also, have the building sitting on something interesting looking, even if it's urbam, the ground its sitting on can be busted up or rocky and jagged, here's some stuff to inspire you
