This is a better picture of the blue half feature wall! And the olive is behind it

Hi Fabulous Pink, Your pendants shown here are quite formal, so with that in mind, I would actually go for the more formal 'first' floor lamp pictured. The blue and grey cushions you previously posted are also more informal in colour and image, (especially the 'coral' shapes) so do not immediately tie together with the pendant selected here. That doesn't mean you can't introduce some blue into the room. Just consider the 'theme': is it formal, casual, classic, modern, eclectic, etc....and stick to that. It can be a bit formulaic, but if you haven't any experience, it is a more fool-proof way and you will most definitely develop ideas as you go, as Susan suggested, but you don't want to make costly mistakes or end up getting totally lost or bamboozled. Re the scatter cushions above, I like the texture of the first two but you will also need to add a solid colour (maybe this is where the blue comes in - perhaps in velvet, so it adds a softness as well as texture) and a throw rug in similar tones.

Hi there I think that adding in wooden decorations and real/fake plants can help bring a bit of life in to your space. And the tones of plants and wooden/nature looking items work really well with neutral colours. They can be both cheap and expensive depending on your taste so finding a bargain or something to suit your needs should be quite easy. If you want a more elegant look marble decorations even if small can be a great way to add a look of class. Candles are also a great way to add in some nice smells to invite people into your home. Keep in mind that sometimes less is more. Don't overdo it and have some fun! It's nice to shop for your home.

I'm surprised to admit I really like the brown. I usually don't like earthy neutrals of any shading but this one is ok, it certainly provided balance for the dark furniture the previous owners had. I love the idea of the side table at 90 degrees to the start of that wall to create a reading nook/dining space and redirect traffic. You could get something reasonable tall facing toward the glass doors to be storage/extension of the kitchen so there is a sense of connection. You could then put paint, wallpaper the back of that cupboard and put up the mirror and a little table for keys. Or even have matching bookshelves back to back and use the one facing the front door as a 'wet' room/shoe storage. Ikea sells so many great units that you can tailor the combination of size and shapes open and closed to get just the right look on each side.If you do this you have to screw the two units to each other so that stand straight and appear as one. If you did use the nook as dinning space you could have all the serving/special stuff in that cupboard so you dont have to go far for setting the table and leave the kitchen cupboards for daily use stuff. When I first moved into my big home from a super tiny apartment I just laid out what I had (plastic dinning set and all) as best I could and moved them around every few weeks till I got the combination of how to use the room right. Then I went and bought more/new furniture over the next 6 months.
