Hello,
Although you have a pretty subtle color scheme which is good as a start, your textile can be a bit more studied, as a potential I would advise you to make your curtains start on a higher length. The higher they are the more grand the space looks, also your space could use an accent colors for textiles in general.

It needs lamps, plants and perhaps pictures, as I can't see the rest of the room. In short, it needs your personal touch.

From what little I can see... no lamps, no accessories, no art? No color? Looks like a very nice room with lots of unfulfilled potential.

Also definitely what ilesliemy said is very valid. You need some greenery and art to show your personality.

When you get home, do you feel like it's your space - your sanctuary? May we see other views of the room? In your idea book, I see touches of pattern. Would you like pattern incorporated in your room? Do you have a favorite piece of fabric, art, or accessory that can be an inspiration?

The space is stunningly beautiful, but you only show us one view. It appears obvious that some type of floor lamp is needed for this grouping. I have added one that fits with the established style.
