I’m not really qualified to comment as I couldn’t do anything like this myself.
BUT, if I had my arm twisted up my back I would say that the foliage on the tree to the left looks a bit odd, although I realise that it could be a tree that I am not familiar with. Seems a bit dense to me. Have you got a reference photograph?
And I think that the grain on the wood could be reduced by at least fifty percent.
Lighting wise, is it perhaps a bit to light underneath the overhanging roof?
Model is great, though 
cheers

Hey
The picture does look good, few things i can say by focusing on a bit everything, take what you want in it, it is your drawing
I agree with synkrotron about the wood, why don’t all beams have the same texture detail level? Try not symmetrizing the texture?
did you put stone on the roof? is that meant to be shale?
Trying to go lowpoly? If not how about trying to get a bit more volumes in the chimney?
how about moving the camera focal point to the front of the house and not the back?
Maybe what is a bit off is the difference between the detailed ground/grass/tree and the sharp squary shapes of the house, it feels a bit like mixing two styles
Maple tree in foreground and pine forest in the background?
The door iron texture is a bit repetitive, the handles a bit small?
The windows (especially the left one) feels too shiny to be real, wouldn’t be surprised to hear a huge crab came to steal it
Everything looks off. Starting with the foliage. It lacks volume and looks more like a small bush than a tree. The wood textures on the house are too simple and unrealistic. The textures on the rocks are all the same and blurry. The color of the grass and their uniform placement is off. The camera lens blur makes it look miniature.
I think this is really good. I would say you could do a lot with a little more lighting. Right now it is really evenly lit, so nothing draws the eye. If the focus is on the house, then light that up. Grab my attention. That’s where I would start first.
A lot has already been said that I would agree with. The texture on the cladding looks like wood at the correct scale. The wood on the facing doesn’t. The grain is too big.
Also, is this supposed to be a miniature? The depth of field is making it look that way. The house should be in sharp focus. The rocks in the foreground should be too. The trees in the background might be out of focus, if they’re large trees far away. They kind of look like small bushes as they are.
Use an empty as your focal point with the depth of field and position it at the front door of the house.
Are you using an HDRI to light the scene? or a Sun light?
I dunno: I personally still give my opinion on uploaded works even as a complete newb to Blender: anyone with a critical eye for aesthetics can usually point-out improvements that might be made - even just from a standard visual-art perspective.
Even not knowing anything about the software, you never know what someone might spot that others overlook and at worst, you might end-up with the same issue being repeated by several people - that’s not a large price to pay for more eyeballs and more brains analyzing an image for possible problems.
Some things come to mind:
- The building needs a bit more color variation.
- You might want to add a bevel modifier to some of the bigger beams.
- The lighting on the beams does seem unnatural, you might want to give them
a darker color. - The stone textures are a bit flat. One trick is to subdivide the mesh (it doesn’t take much),
then add a displacement modifier with the stone texture. You don’t need to recreate all
of the detail from the texture in the mesh, just enough to improve the outline. - The wood grain on the biggest beams seems too big.
@AyKay Its a nice scene, but I agree with you about its feel. Its all about scale here. The viewer needs visual references that his/her brain can classify get a feel of the scale of the presented scene, to judge if its now a big house or a toy in a sandbox. And if that is lacking these information or details are hinting in different directions you get this sort of strange feel. The grass has hardly any bending even if it is 2 stairsteps high. The wooden texture of the beams is far too big and makes the house look small. Think about how big the wooden rings of that tree it once was must have been to produce that pattern. The tree to the left is so dense and has giant leafs compared to the height of the house entry and eg the height of its balustrade. A single leaf has almost half of its total height. Rocks dont work well generally to give a sense of scale, as the have self similarity on many different scales. The tree at the front works much better. It gives a much better sense for what you want to achieve, the same is true for the trees in the distance. I’d also take the blur away as it also doenst really fit. Fixing these issues is far more important than its lighting. Should not be that hard to fix, good luck!
Edit: Wow, didnt realize this is already a year old. I dont think it makes sense to reawake such old threads.
