Thanks all - our belongings arrive this week so I will have a go at transforming the space with what we have then search for new things to add. We have quite a bit of art with strong yellow colors and also a Tibetian Chest with yellows and greens. Thanks again!

Your picture display looks lovely with your sofa and will look better if you bring it down because it's a bit too high above the sofa ( unless you plan to keep adding to the picture collection below from where your pictures are hung now) and in that case just keep in mind that multiple frames look best when arranged in a diamond, rectangular or square shape and spaced relatively tight, like 1-2 inches apart. A looser grouping can work for a more casual display.

OK - I'm a beginner here on Houzz so my opinion isn't worth a lot but here it is: the room is a bit bland and lacking in character. I think you have to find some pieces you really love to bring it alive. All the suggestions are good for widening your horizons, but ultimately, you need to find things that matter to you, because it's your home and not a magazine photoshoot. That said, if it were me, I'd throw a couple of small, colorful rugs down, and put either one large painting or three smaller ones over the bed - not in a line but at different heights - to break up the binary look. I'd also put something on the wall above the heater. Then, play around with a few cushions and maybe a quilt that picks up some of the colours in your artwork.

If it is a casual buffet type meal you don't need to go over board on the dinner table. I would suggest a lovely table runner a pose of fresh flowers (not high so that you block peoples view across the table). Some lovely place mats, standard silverware and glasses all set out and a couple of very simple candle sticks - I also love the idea of the mini Led Fairy lights but maybe around the room (perhaps a mirror if you have one in the room). If you have napkin rings or can make lovely napkins shapes out of origami, that adds a little bit of class and perhaps a small chocolate at each place setting. Don't go over board. After all it is the company (and the food) that should be the star of the night and you need to relax as well. Not every decorative piece needs to be on the table.
