I would suggest taking everything off of your mantel (bar the lanterns), and mounting the mirror above it to the wall - don't have it leaning. The cupboard in the middle of the fireplace really needs moving... if you don't have enough storage in your side board without it then I'd suggest replacing both units for one bigger storage unit. You could also get rid of all your cushions, and replace with some brighter ones and a sofa throw - I would also move your sofa with its back against the window. And as people have said above, the rug is too small for the room, by replacing this for a bigger one it'll bring your space altogether. And lastly, check out Desenio.co.uk for artwork.

In planning terms there is a 45 dec rule i.e draw a 45 dec horizontal line from the centre of the nearest first floor window of your neighbors house towards your house and your first floor extension should not pass this line

Sorry super urgent!!! How much gap looks best above this console?? Should the painting be lower than the candle holder or higher? The above are 8" and 6.25" . around 57" from the floor.. or should I lower it slightly to 6" so there's slightly less gap? Guy hanging it soon..Thank you!

It seems to me the space above the picture rail should be clear of fittings or any decor for that matter. I'm also having a hard time picturing wall lights and alcove shelving on the same wall. Just because they are there now doesn't mean they should stay. Some lights on an extending arm could look nice, depending on your style. Or flush LED lights if you want to light the shelves. Much depends on the design of the shelving.
