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!

Is this picture taken during the day or at night? If it’s daytime your kitchen must not get much natural light. Go for white cabinets to reflect as much light as possible to brighten the room up. Boring but timeless & always looks fresh. For colour you could do a splash back, or just add colour via accessories such as a bright kettle/toaster set, tea towels etc., easier & cheaper to change if you get tired of it.
