It's looking very nice so far. I think the problem with all the browns is that you emphasized the color of the material too much while neglecting the lighting. This can be a really great scene if you get the lighting right. For example, look at the fourth reference photo, where the light source has a dramatic effect on the scene. With two light sources with different color lights it will be a bitch to pull it off well, and may not look all that good.
If I were you, I'd get rid of the window and keep the stove, which looks really nice in the second picture. Maybe draw a second door on the left side of the stove to light the benches. Be sure to take the slits in the door into account when shading, and darken the parts of the room away from the stove. It will be a lot of work, since you will not be able to use shortcuts (every board and bench will be different due to their unique position in relation to the light source).
The rug looks like it's top down perspective, maybe it should be more like this:
