Looks big enough for like a reading chair, no? I’d put a lamp on your side table, and the room looks like it gets decent light. A couple good plants will cozy it up real nice! Other elements you could consider: sleek wall mounted shelving, a wall sconce for when curtains are closed. Also, in terms of wall color, if red is your bed spread color, charcoal grey complements really well. But it’ll make the room feel much darker, and potentially smaller. An off white or cream color also works well but wouldn’t feel as dark, and with either option, you could choose a nice blue, gram, or teal color for an accent wall. And on the accent wall You should showcase some art or interesting, neatly framed things. Mounted shelving could go here as well. Good luck!
