I like the use of green and white colors. I think green is one of the colours we'd like to embrace in our bedroom. We also have some reds (complementary colours so not sure how that will work out). The idea of a wallpapered wall as a "feature" is cool, and in this case, I think the white bed head really helps to balance what I think might otherwise be a very saturated wall space. The order of "layers", ie, green wall, white bed head & side table, green bedding gives a sense of greater depth to the space.
I think this wallpaper could work as an accent wall in the bedroom.
