The landscape is featureless, soulless and uninspiring.
Is this correct and natural?
I don't like it here. It's just a vast expanse of barren land. The landscape is less than poetic here.

I am not a teacher or a native speaker.
Try:
It's barren land. It's uninteresting.
(Note that "just a" and "vast" don't go together.)

But a vast expanse would have to be a considerable amount of territory. How do you put "just a" in front of that?

Very easily in BrE.
Bob: Do you like the new Heritage Tower in the middle of town?
Jim: No! It's just an enormous grey monolith!
Helen: Is the national park worth visiting?
Sarah: Not really. It's just a huge expanse of brushland.
Maybe it's another transatlantic difference. BrE would use "just" very readily in such statements. As I said, "just" means "nothing more than" or it's a way of saying "That's all it is. Nothing more interesting than that".
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
