Greg think you have made a great start, just needs a few colourful statement pieces. Firstly the chest of drawers are fab, my suggestion if you like them would be to utilise them in the lounge either side of the radiator under the window, for storing what looks like cd's the other side of the fireplace in these. You could put the existing cubes either side of the two sofa's. I would ditch the rug in the lounge, and get something bold and bright such as cobalt blue with orange/yellow. In the bedroom, keep the IKEA drawers and paint them either black or dark blue and have them adjacent to each other on the back wall opposite the bed, with the TV on top as someone has already suggested. The art work is great, but would swap it over to where the mirror is and move that elsewhere. Again ditch the rug, maybe an animal skin would work well in here, keeping a masculine feel. Pick some of the colours from the artwork for a well chosen throw and cushions for the bed, and don't be afraid to use some other accessories such as vases, lamps and dare I say candles!

Hi Mark. see link https://www.mrperswall.co.uk/wall-murals/collections/fashion

That looks lovely! I think it would be a good idea to use the same tiles as the floor behind the vanity unit but then again the photo you uploaded with the dark walls and white tiles looks great. The only reservation I would have with that is there are a multitude shades of white and you may not get the right white for the porcelain. Also that wonderful bath might recede into nothingness with white tiles behind it. Were you thinking of tiling or painting the wall behind the bath?

It depends on what else you have in the room, the sofa colours etc. It looks to be a really nice room with some lovely features. Personally, I wouldn't paint it all a blue or a dark colour as East facing rooms can be gloomy on an afternoon. Have a look on instagram, there is a total shift away from dark interiors towards more neutral warmer ones. Not that this matters, but perhaps a year of lockdown has made a difference to what people want to live with.
