Calm Down Your Senses. Well we tend to use our phones or laptops before going to bed and this direct exposure to light can prevent you from falling asleep completely. You would need to mellow the lights a bit in your bedroom to a soft glow at least an hour before going to bed so as to enjoy a sound sleep. Furthermore make sure to draw thick curtains across your room's windows to shut out traffic and streetlights. As you prepare to go to sleep at the end of the day always make sure to keep your mobile phone away although close enough in the case of an emergency rather than keeping it by your pillow.
If you're implementing wall papers in your bedroom it is best to clear out any mess or clutter you may have our your walls. It goes true specially for small bedrooms usually wall paper decoration along with other wall items here and there may look messy. Always remember that a clean bedroom always looks much better and appeals more too.
The art of using color contrast really helps. Anything with a light wall color dark rugs or a dark unique shade of flooring with light color curtain and relatively darker shade furniture always looks good!
