The artist seem to nail that style really well.
It kinda falls in the uncanny but it's meant to have creepy vibe to it.
But I feel it's part of the charm of this aesthetic.

I don't know why but I just find these sort of semi-realistic/pre-rendered animated stills that you find in games like fallout 1/2, myst, abe's odyssey and the backgrounds of early resident evil games so appealing. I really hope that some indie devs use this sort of style to make an fps that looks just like this.
