The flatness of the house is because you are repeating tiles and mirroring them, when Rare wouldn't. The official barrel boss up there, despite looking symmetrical, is not - there is only one side being shaded - but by flipping pixels around, you break the shading seam, resulting in "pillowshaded" assets (shading either coming from both or no sides)
it doesn't help that the vertical logs of the house has that faint blue shade for the cristalline river reflection pointing INSIDE rather than outside. Considering the SSB level, on top of mirroring its orientation, you should also change the color to a reddish or dark orange hue to match the sunset BG.
