i posted this also on the LW forum, not sure where you are following...
here a few tips to refine your work: first, please, turn the lights off, the sunlight is bright enough or is a sudden eclipse expected? maybe this is the reason for the astronomical observation monocular? btw. this is the most abused archviz interior accessory of any time...
do you really need that many lights in such a small room? spotlights, ceiling lights, wall lights, all of different kinds and styles. maybe reduce it to less types and to less in numbers.
another tip is to add some modeling detail to furniture and windows. for example, some depth and beveling to make the window door handles and frames look less flat. maybe try to give the large dark wall furniture piece a bit of detail, some slight subdivision line to suggest a drawer or some doors is enough to make it more than just a flat mapped volume.
to add a bit more of interest to the image, an idea would be to open the sliding door on the right side a tiny bit to let nature and fresh air from outside come inside... this makes the curtains slightly move... etc.
overall tonal balance of the image is a bit unequal, imo. you can make the wooden wall furniture a bit less dark to show more of the texture and the floor a bit darker. try to use a better bump setting and add a small dark line or gap where the floor is touching the wall. in reality, wood needs always to move and therefore is never attached like 'glue' to a wall...
also desaturate colors a bit to make the image look more real. if you like, keep the chair really pink so it will outstand from the rest of the furniture and give the image that particular touch. make this like the main 'character', the 'hero object' of your composition.
ok, that's what is going through my mind, hope you like the tips.
cheers and keep us updated
