Hi,
Nice start. The image has potential and I think that you should work on image contrast and overall color first.
Try to make curtains less transparent to achieve some contrast (it's too bright, blended). Think about wood color from the left. Maybe to try different color (to make complement with the scene) or try some other foreground element. I think you should remove the plant from the right, you should let the image have some breathing space.
Finally, add more details: light on the ceiling, make rug more natural (bend it), add some person etc.
