first of all i must admit that i mixed up your rendered image with the reference -.- stupid me :o
(to be true: i favor your images ! the reference image is too bright to my taste. in order to that i prefer the darker floor of your first render )
but there is still an improvement ! -now, in the 2nd render i can see the frame of the picture as in the reference image
little things to improve: the vase needs a more glass like look/material (don´t know if you deliberately leaved it out, together with the textures, for faster render times?), the cupboard is higher (and its color brighter) than the reference cupboard.
as isaque says you could add the missing books.
because of the illumination (and/or material?) the picture in the frame seems to bright -i think you could fix this with compositing (material index -> hue saturation or bright-contrast node ; if you don´t know how it works i could maybe send you a tutorial link)
materials: maybe you should decrease the roughness of some materials, this may results in less brightness all over the room.
shadows and lighting: try out different distances of the light sources to get “sharper” shadows
i am looking forward to another render (maybe with textures^^?)
