not bad but:
-the problem this it is not a WIP, if you are doing a progressive work, finish the most of the modeling first, then play with texturing, then lighting and render, this keeps you focused on the task that needs to be done.
-to cure this first search through the internet for a similar scenes then try to see what objects needs to be added.
Yeah perhapse you are right, but I just like to see what I’m working with 
This one is supposed to have like a hot mood.
This one s supposed to have a cold mood. Wich do you prefer?
Prefer the warmer personally.
If it were a real room, I’d probably move those seats a little further away from the wall so they wouldn’t scratch the paintwork…
I kinda like the second one…
The scene is looking good
About the colors…
In my opinion the warm one looks more natural in terms of the amount of lighting you have outside and it gives the feeling of a sunny day, but…
The contrast between black and red in the cold one looks more interesting, and maybe you could experiment with the lighting, if the lighting would reflect a more cloudy weather than a very sunny instead it would fit better to the cold mood that you want to express.
Also, I would increase the saturation a little bit in the cold one.
Thak you all. The feedback you gave was just what I needed
