The first room I’ve ever created in blender and also the first thing I’ve created on my own just with a simple image from google. 
Right now it’s still pretty empty and I could look for a better Sky Box but I like it so far.
Feedback appreciated 
Samples: 1000
This is very nice, the only thing I can see at a first glance is that you could organize the screen better by adding empty and parenting objects like the bed or the table. As an overall it is a very nice low poly room 
edit:
if you decide to join your meshed instead of parenting them it could help you to make vertex groups
I like what you have done, especially the piping on the headboard. Agrees, a different environmental background would add a different flavor to your scene but, what you have currently seems to work well.
You might want to consider pillows or a bolster for the bed and maybe a couple of pillows on the floor? Something it a complimentary color to the nice painting/art work you have on the wall.
This is a matter of personal taste. For my tastes, I would of chosen a much lighter color perhaps a medium beige or tan for the walls something to offset the darkness of the floor. Something between the white of the furniture/ceiling/other window (? on right wall) and the dark brown of the wooden floor. It would be what I would look for and it probably would be something I would have to tweak to get it to look just right.
A quick search on the Internet (see link below) perhaps the H or I swatch on the left might be good colors I would play around with. It looks like it lists CYMK code on the left, with RGB, & Hex settings on the right. It looks like this is a site to sell you a book but are many other color palette resources out there. Again, it is a matter of personal tastes.
Great job! It is a really nice scene and look forward to see more of your work. Thanks for sharing it!
Thanks for your long reply! I’m looking forward to add more to the scene, maybe a tree outside of the windows/ glass doors, books on the table and of course pillows and a blanket. I personaly like the color of the walls, maybe a bit too dark but it represents a nice contrast to the picture/painting I guess. Anyway, also thanks for the link.
Sounds like you have a plan! So, keep us updated on your progress.
Yep, color and creativity is personal choice, as it should be! Everyone can offer opinions but art is up to you, the creator! 
Keep up the good work!
