Without context, knowing what it will be used in, it's hard to say. Might be perfect, since it possibly matches the environment's style in which it'll be placed.
Can you post a mockup yet?
Is it wise to analyze this isolated?
COLORS
All dark, all muted. Uninteresting.
Try mixing colors from all over the thing to other parts. Have you heard of the "all colors everywhere" ideology? It says that limiting all of one color group to one element or section may not be such a good idea. By spreading your colors around you're able to achieve stronger harmony.
Very little value (darkness/luminosity) variation.
Reads as excessively 2D and flat. Thanks goodness for that roof shadow at least.
SHAPE
Basic rectangle.
Monotonous repeated elements.
Except for chimney it's symmetrical.
Would it be appropriate to innovate some more interesting architecture? Different levels of roof heights, smaller annexed rooms that break up the rectangle silhouette.
Look here. Scan all the cabin images and break them down into their MAIN shapes. Notice how they're put together.
How about some decorations, some ambience?
Meat hanging up to dry.
Farming tools hung up.
pair of boots
barrels
plants
rocks
Your door. At 1x it doesn't read well as a door. Looks like the doorway is blockaded or something. Reduce contrast of lines inside door.
Those hinges would read better if they were logically spaced - why is the distance from the door's top and the top hinge not =equal= to the distance from the door's bottom and bottom hinge?
