If you think that photo wall murals are very 80s and cheesy, you need to rethink you opinion, because they are making a modern comeback. Paired with simple elegant furniture and sleek flooring, the murals can actually look great and even add depth to rooms, especially those with limited space and / or lighting sources.
Like with everything in home decor - it's all about the right combination and incorporating it into the space itself. If you do go for a forest photo - try to have more natural wood elements in your space to support the mural. If you choose to go for the sunset view, the best would be probably pairing it with Miami style art deco furniture.
One thing for sure they provide lots of character to the space with a minimum of spend (for about $100 you can get your room transformed into a magical forest or a sunny beach). So give the 80s murals a chance and see your space getting a modern makeover... with a twist.
