Yes.. I think you should paint, but... Why not lime wash the walls so you keep the look of timber and get the light, on trend Scandinavian aesthetic. I would go for a very light grey tint with a bright white ceiling and trim. Your fireplace and the deer would be great with this look: a rug and some white and grey cushions of differing textures would bring it all together. Coffee table candles would complete the Scandinavian look. Great room by the way!

A few simple steps can give your room a lot more vibe! Try pairing the drapes with sheer curtains, that will give the window more depth. The tv wall could be your accent wall, a dark blue would actually work very well. If the TV has backing, I would hang it on the wall, a few inches above the furniture piece. The two frames above the white dresser should go below the wall clock. Instead, a large art piece (about the length of the dresser) would complement that wall much better. I would also replace the coffee table with a rectangular, heavier glass and metal table, placed in the center. Also pillows. Pick up colors from your art work and the accent wall and use those to find pillows to decorate your sofas. Hope this inspires :-)

We have been renovating an 80's home with a vaulted roof in the living/kitchen/dining area, something like your picture. We needed to make the space look bigger so we opted to hang our tv from the roof using an Adtec tv bracket in white, pretty nifty unit, all wiring, aerials etc go up the mounting pole and through the roof. The unit also swivels 360 degrees which is great for any view point in the room, including our outside area. We had a tv unit custom built by Jarramar Furniture which is like a rather large floating cupboard. The unit has 2 draws and one cupboard. All the cords etc come down the wall in the adjoining room behind the door, neatly packed into duct and back into the back of the floating cupboard. It's very neat and tidy, keeps everything off the ground and makes your space look bigger. Both Adtec and Jarramar have websites where you can check out their stuff. You just need to ensure your tv weights are ok for the Adtec unit your wish to purchase. Good luck with your design.

Personally , I wouldn't use that wallpaper -- it doesn't suit the apartment style IMO . I assume she wanted to add some focus and colour , but to me it doesn't work . To make it work ( or at least not 'jar' ) if she does insist on the wallpaper , pick out the burgundy or red of the wattle flower ( or whatever it is ) , and do a wall opposite it in that exact same shade , or maybe the kitchen area if you have good masking skills . The animal skin rugs look great , but the couch is 'lost' -- add cushions in the same red or burgundy as the wall , or go even brighter red or burgundy . Rest of the walls can be left as they are ( depending on wall condition ) or any similar neutral ( aka bland ) grey or cream , or possibly even a light steel blue .
