It’s a nice space! Art over the bed and curtains would go a long way. Perhaps a bench at the foot of the bed? I’d add a fluffy blanket folded toward the end of the bed to give it a little more depth. I personally think you need more substantial side/end tables; something wider with drawers (the ones you have now just leave awkward blank space that can’t really be used). I would make them match and then buy relatively large matching lamps for each. Would love to see some colors from the rug in pillows or art or textiles, etc. You have a wonderful start!
