I'm not a fan of neutrals or brown/grey, but the ChatGPT suggestion from @Upsetbetty is lovely and makes the space feel far more contemporary/bright with some personality too.
@MooMooAchoo I don't think the brown carpet is an improvement, sadly, but all isn't lost if you add a large area rug (should be sufficiently big for the front furniture feet to sit on it) with pattern/texture.
I'd want to colour drench the woodwork to match the wall colour (although I would have chosen a more saturated paint colour, but that's me!) as I find the orange joinery very dated. I would also return the sofa when it comes - the examples posted by @Upsetbetty upthread are far nicer/modern, imo, than either of those posted by the OP.
Apart from the ridiculously high clock which has already been addressed, you need to be injecting as much of your personality/style into the room so that it doesn't read as bland/bleak which is how it currently comes across. Art, lamps, books, plants and textiles (curtains/cushions) are all good ways of doing this - but whilst others can make suggestions, only you know what 'speaks' to you in the form of art/decorative objects etc. Even if you lean towards minimalism, a few carefully chosen items will give your room character and personality.
In our home, we have art (and other stuff!) that we've collected over many years - we know what we like and often we take ages to find the right piece. Other times we just stumble upon the perfect item.
What curtains/blinds are you planning? Or do you already have them? Fabric is another way to bring individuality to a space and there's so much choice out there - not just pattern if that's not your thing, but texture too. Cushions and throws can be an inexpensive way to add pops of colour, not to mention making a space more cosy and welcoming.
