Hey all!
Thanks for the great advices! I'm finishing up the living room as only a few items still need to be purchased (lamps, mirror, etc)
I finally did not go for the mural I was talking about at the beginning if this thread. I thought it was too big, I might get tired of it, and most of all, it was absurd expensive. Instead of the mural I am thinking about a large rectangular mirror that would reflect off the sunlight from the front window.
Of course ideas are still welcome!
On the other hand, I purchased brand new furnitures such as 2 swivel chairs custom made for me

a extra large 3place leather couch ( I treated myself I bought real leather not faux leather or bycast either) . Was expensive but I really don't regret it! Now I also have a nice 55in LCD facing it ( mounted on the wall) and my Linux htpc connected to it . I also bought a large coffee table and a smaller end table.
So overall I think I'm doing fine ( finally)... Next step might be to replace the carpet by hardwood . To answer Alyssa's question ( I like your name btw

) I tend to go for modern or European style rather than classic or country style.
I'd post some pictures but my camera died and I'm looking to buy a new one. For now I only have my iPhone's camera... Not great!
