I like the design of the main home/cabin. In my opinion the garage and free standing... garbage can hut...? do not fit style-wise with the home. That is just an opinion and of course everyone has their own:)
The thing I notice about your render is the composition. It feels a bit flat. as if the building were sitting on a perfectly flat plane and just rotated a bit. I would suggest rotating the view a little so you are looking slightly up at it. It feels almost as if a 2d view was just spun on the vertical axis.
Nice curb and driveway. Although I think the asphalt is too light.
Another thing that would help the composition would to be to add some foreground plants or bushes and plant some trees behind the camera to cast some shadows on the lawn. The lawn as it is, is too flat and too lime green to be convincing.
How about some furniture on the upper deck?
The roof texture is not great.
The bench is kind of in an odd place. Would you be staring at the garage wall with your knees under your chin if you were sitting on it?
The bushes look like photos of bushes sitting on a flat plane. If you add some bushy small plants at the base of those bushes it will help them feel grounded.
Do not be afraid to add some more plants and shrubs. The very limited amount you used feels like the home owner ran out of money before finishing the landscape:)
The planter thing hanging from the deck looks lonely. Such a symmetrical form, one would think maybe hanging two of them.
I have never been a fan of cars parked in front of houses, unless I am selling cars, not homes.
I hope you take all of that as not just criticism, but as a constructive critique.
