I’d stick with brushed steel or nickel.

I agree, brushed nickel.

What do you think of these.

Great space! I think I'd stick with nickel (or stainless, which works fine with it). I'd use a pull, because some of the doors will be a stretch, and keep them light to match the feel of the room.

Be sure to order one sample of each contender, so you can actually feel them in person.

I'd have no problem with polished chrome or polished nickel. Not all of the hardware has to match. You've chosen a special wallpaper and I think you need to up the game with the hardware to make the space feel as special as the wallpaper.

We'd also suggest sticking with the brushed nickel or stainless steel.
