My first "real" 3D architecture assignment - Living room

[Mythix]

Hello!

So, yeah, I've been quite busy.

First off, let me say I knew nothing about lightning and textures when I started this so I've done that part over and over again, and I'm playing with daylight system on this scene.

Please, critisize it, but keep your critics constructive. This is my first obligatory assignment for school, so please bring up ideas and so on for it.

Afew facts about it:

I can't find a leather bump map I'm happy with.
I can't get the specular level to work.
I can't get the "lightning holes" in the roof to glow in mr.
I hate my curtains. I have rendered them quite alot of times now but I'm never satisified, I will try all the cloth modifiers later.
I'm not happy with my overall lightning.
I want to take this to the next level, but when I am happy with one thing, another thing gets effed up.
Any critic or hint which will make this more realistic is appreciated! <3 So yeah enjoy ^^

That being said, please, comment. I will post the picture I'm imitating later, I just gotta find it, the assignment is to get as equal as possible, or better

REALISM ADDED!

Here you can see the development:


And yeah here's the image I'm supposed to make, however I thought the colors was lame as scat so I changed that a bit.
