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.

I love what you've done so far - I would, however, change the light frame to a black one and add matting that is the same colour as the red in your hallway print that will tie your hall way and dining area together in a subtle way as well as making the print bigger - you could take the matt out by upto 15cm (more if you're brave) and the frame width of between 2cm up to 10 (again depending on how brave you are). As it's a rather large wall you can go bigger with the matt and frame as your wall can take it and you've been restrained with the rest of your colour and material pallet. Your plants are lovely but they're lost down on the floor in the corner - if you can boost them up (I've found pots turned upside down work and have also been known to use old pottery sewer pipes painted - they're totally clean of course!) so that they're a feature rather than an afterthought.

I love your fireplace, and your tile selection, I can really see those tiles blending beautifully with the rest of the room and being a lovely feature as well. I have a similar fireplace (two tone brown brick) but it's in the living room, so I used furniture to hide it's mouth but will eventually be putting in a gas fireplace. I'd love to see how yours looks once it's done, you've inspired me to consider tiles as a base feature as well! :-)

My mother has one of these as a candle holder! I will ask her for you UPDATE: she got it from a local crafts store in Mullumbimby - no name or brand on them! Sorry I cant be of more help
