Like you said, you obviously have a light issue in the room due to the addition of the corner ceiling light and the need for sheers. Maybe paint the ceiling white. Definitely replace sheers with white plantation shutters and add your beautiful chosen pendant lights over the table. As the table is long maybe you can have the light above the window (and if there is a third one further along) moved in to have them over the table. If the pendant is very large have only one or two and remove the extra light/s altogether. You could also possibly add two wall sconces to the wall opposite the windows depending on the overall room. If you physically can't electrically fit lights on the walls now consider battery candles in the glass flutes. This would give lovely mood lighting. Have the white plantation shutters with no additional curtains but have a very large striped rug either the same red as in your photo with creamy beige to blend with lighter wall; or a light blue and white/ creamy beige rug. The light blue stripe would give a relaxed sense to the room. You may need to have these rugs made up. On the table, change to a larger silver tray and look to improving its content holders to silver and glass, light blue china and one low wide rounded fresh flower vase in silver. For dinner, remove your tall vase of roses and replace with a couple of large glass fluted candle holders with silver base rims with pillar candles either side of the tray. Best wishes.

You need to post a photo of the lounge.

I have been looking on Houzz and got a couple of ideas for the bedside tables (without spending anything!) .. Please let me know your opinions on the following... Attack the existing ones with a sander and take off half of the white paint, exposing the dark brown underneath, and making them look like they are meant to be shabby. Take them both out of the room and replace with a stack of vintage suitcases on the door side and an old weathered timber folding chair on the window side (got these in storage so wouldn't cost anything!). The chair would have to have something on top like a box to hide the usual bedside table clutter in, I guess. 3. Any other suggestions? Don't want to spend any money here if I can help it! I have access to plenty of old pallets which people seem to make amazing things out of but don't know if that would be too rustic in this room?

Just had a look at the entire project, I'm obsessed with the blue undertones! Made the space pop with colour!! :)
