Of course you can use any fancy wallpaper you want but I assumed the reason you were asking if it was "too much" was to avoid making an expenxive mistake. If you want to choose something that works vs something you like that doesn't work, that's your decision. The wallpaper is beautiful and would look lovely in a bedroom, dining room or powder room but not a den with heavy leather sofas. The wallpaper and sofas don't compliment each other. Please assert your femininity in another room--a den isn't supposed to be feminine. It would be like painting the walls pink. Find some magazines with pictures of rooms with leather sofas and notice how they've been accessorized. Do you want an honest answer to "does this dress make my butt look big" or are you going to wear the dress no matter?

The background seems to be a soft calming pale warm grey which I would try to match on the other walls and pick up the yellow in some of the accents such as lamp bases, curtains, cushions, a throw for the bed or even upholster a chair or long bench for the end of the bed if there is room for it. I would use a deeper tone of the grey or an aubergine in some other accent pieces, perhaps the bedhead or bedside tables.

Hi Gerty, I would definitely recommend a neutral textured wallpaper if you didn't want to just paint the walls either side. Harlequin do some really nice ones that would work against the busy fireplace. Or you could use on another wall and paint either side of the fireplace, hard to say for sure without seeing the whole room. This has a slight plaster affect which slightly emulates the pattern in the fireplace... This one is a metallic texture which could look really nice... This shows how the textured wallpaper will look but I would stick to a neutral colour...
