I think the image is too much dark in inside no proper gi or less support of light from inside though the source of light is from out side but u need to give the the support from inside also in the form vray plan light of simple omni secondly no contact shadow of carpet with floor the models are also not detailed plus see that plant pot on window its going some thing wrong there with there contact light is there a bulb inside the plant pot i guess so

all the wall hangings looks fake and in the air as no proper contact shadow is visible as the whole image is going in dark in that area plus see ur texturing on sofa its tiled dont do do that do some post work in photoshop man and sorry o say this also that ur carpet looks very very thick not so good but over all in first sight looks good but try to impove.
