Paintings in bedroom and generally in any room are a very important element, I’d say. A painting either fits somewhere or constantly irritates.
In a bedroom I’d suggest to use something that will help to create a better relaxation atmosphere. Or maybe a painting will be exactly such a detail that will wake you up from sweet dreams and you’ll be ready for a good beginning of the day? It's up to to you! Maybe a picture will be a focus of a room and a decor of almost the whole wall or maybe it will be just several fragments that will help to have an appropriate mood?
I’ve collected some examples how the pictures can change an interior and an impression about a lord of that space. Let’s see different picture application variants and I believe that those who doubt will definitely decide what you need!
