Unfortunately, you have made the television your focal point, the television should be on the wall where the art is. So put the art where the TV is and put your three seater lounge under it. the two single chairs go directly opposite the TV, also the ottoman should be a rectangle and the white chair should go to the other side of the room near the large window with a small side table as a reading nook. The furniture can float in the room and does not have to sit right near the walls. Also I would mount the TV on the wall and have a full width timber floating shelf (ideally with storage in it) about 30cm top to bottom. Hope this helps and the room appears more open and inviting.

Hi Chris, Lovely house! Art is always a such a personal choice but large scale artworks are our speciality and we agree that's what your space needs - something with impact. I'm attaching a link to the client review of a project we did in a similar setting which worked really well. http://www.houzz.com.au/viewReview/297646/signarture-review That piece was a 800H x 2400L perspex artwork but we create all our artworks bespoke, in whatever dimensions / colour / medium works best for your space. You'll find triptych versions of this design in our online gallery which would also work well - and can cover an even greater span. This link will illustrate the options. http://www.signarture.com.au/collections/treescape-perspex-artworks/products/tree-perspex-art-burrawang-magenta-triptych We have many other designs, so feel free to browse our collections, and if you see something you love, don't hesitate to reach out.

You can definitely choose some simple and graphic artworks for your wall. Here are a few ideas you might like. There are some matching leaf prints you could possibly use - Or you could use black and white photography to match the kitchen and perhaps throw in a tall plants, like a potted Mexican bamboo, to brighten up the space-

As I said before keeping clutter under control is the key, get lots of storage ,you said cost is I s an issue. Look at IKEA they have solutions for wall units that you can get in different colours and that in itself will brighten the place. You would benefit from a buffet next to the kitchen /dining area or a large wall unit with lots of shelfs and drawers, coffee table with storage drawers , storage unit with baskets for kids toys and school stuff, once you have this under control start adding rugs if think you still need it. By the look of it you have small kids get them to put things in appropriate place and get some funky coat hangers in the entrance so they can hang hats and bags etc.
