Since you are asking…
The wood is VERY saturated, and definitely too red compared to your ref photo. The wood texture is clearly tiled, perhaps you could tile in PS and clean up the repetition, and then apply that.
The dark wood is VERY dark. Feels like it needs less fresnel and more reflectivity, and just a lighter value to begin with. See how it is looking nicer on the right side where you have some reflection? You could roughen up the roughness even more. I would also try to get the various black-like materials to be slightly different, more difference in their reflectivity, roughness, and fresnel values so they look like distinct materials. For instance, you would think the painted metal surfaces like the window frames and railings would be more reflective and less rough than the black wood-- from the ref photo it looks like the “black wood” is actually black metal. So definitely did not get that from yours. Perhaps a low frequency bump like the ref to get some more variance.
The lighting has no real direction to it. Try the light raking across it, 3/4 backlit is always nice, with enough frontal fill (though clients may want more frontal), or even the high noon photo is better than full frontal.
The colors in the sky are too saturated, don’t seem to fit the scene, and draw my eye too much to the BG.
Some subtle DOF would help if you could get the house sharp and the trees not as sharp.
The edges of things are very hard and fine. Looks like you need some bevels in a lot of places or to use the VRayEdgeTex in the bump slot trick to fake them.
The entire image could be desaturated, and softened a touch, with a hint of vignetting, etc.
Some of the trees have a lot of blue/cyan in them, feel a bit surreal.
The interior light itself looks nice. The balance is a hint odd unless it is a dusk shot, which I think is what you are trying to do-- just not feeling that. The exterior lighting and fill could come down.
Of course this is your creation. So you take everything anyone says with a grain of salt, and put your own flair on it to truly make it yours. It’s easy to get into design by committee, and end up ruining things that way too. It’s most of the way there. Just little things like these, and what others have said could help push it further.
One possibility of tweaking attached. Of course you can do far more with the actual scene. I would still get more magenta out of the sky, personally.
