Kelly - at the top right of your comment is a delete and edit button. Just click the delete on each duplicate and it will go away. I love white curtains in a room, they really add freshness. For a lounge room though I would use a sheer fabric that is more structured and heavier than a normal sheer - if that makes sense. If you use a double track you could then put a thermal lining behind the sheer for privacy at night or for keeping the sun/heat out. It will also keep warmth in in winter. I take it your artwork is in red and black and assume your lounge is black? I'm thinking green would be a good colour to introduce into your room. Post photos when your furniture arrives and we can take it further from there if you like.

What natural light do you get in the room/what orientation? i.e. is it a 'cold' or 'warm' room? If it's a colder room, I'd go with a grey with orange/red undertones to warm it up a bit, or if it's a warm room you could get away with a cooler grey, maybe green undertones to compliment the maroon. Or you could even try a green rather than grey. The Aerobus is a blueish grey so will be cooler. As others have said you would probably want a lighter tone than this for the walls (unless you're purposely going for a dark dramatic mood). 'Miller Mood' is a couple of shades up in the Colour Atlas. Get sample pots and paint a section on each wall, or paint a white bit of card and stick to the wall to see how the light is at different times of day.

I think complimenting your beautiful ceiling with a similar style of fireplace would look wonderful

Its your rug, not gonna lie that's exactly what's wrong. Everything else can be worked with except that rug. I would rather look at floorboards than that rug. Go to a fabric shop and glue a pretty piece of fabric over the top of the rug if money is tight. Make sure fabric has that curtain plastic backing so glue doesn't show through. Also nothing in there has the same colour scheme, character, it comes from different era's, theme's, not sure how to explain it but... Cane chairs look like part of an outdoor setting, Wood chairs look like they are from a dining table, there is different wooden furniture with different stains all piled at one end of the room looking odd together. Then the chairs are too far apart to have a decent sit down and chat. The art is really random as well and not good Centre the small table in the window and put a big fern on it to give it width. It looks like a plant table. Split the room into two sections, use the skinnier end as like a card game area to play bridge or rummy. Use the larger section as your living\ talking area. Hang the TV on the wall. Use the tv unit as makeshift coffee table until you get something better. Put the two cane chairs closer together on the other end of the couch facing the window. Paint over your art pieces, even in white only, just texture the paint to make it look like something. All this is using pieces you already have. Now sit down and decide what look your going for in that room. Modern, Industrial, Farm house because your on a farm and just buy accordingly. Reuse your couch for now and just buy a white cover or cream and colour everything else. Buy some actual arm chairs that look inviting and cozy, throw rugs for everyone but pack them in a basket and don't do what magazines do by haphazardly throwing it on the couch. Like these baskets Extra or out of season cushions in one and blankets in the other. To intertwine modern and old they have to have a common ground? I don't know if that's the word but either the wood stain from modern and old should be similar/same or they have to have something in common besides function for them to mesh well together.
