We have "Storybook City" by Chariklia Zarris, which is a painting containing an assortment of different colors. Such an image is quite ideal for children's room. There is also a grayscale "New York Cityscape, Sunday" by Sir Edward Hulton and Getty Images, which you can use for ideally any room. However, you’ll need to make sure that your selected cityscapes images are mounted such that they add value to your design. Moreover, you need to ensure that the size doesn’t either kill its appeal or those of other wall hangings that you already have in the room. Note that you have a wide array of images of cityscapes to choose from and that you can decide to laminate, frame or have it in canvas. Only make sure that your selection of wall arts is enhancing the elegance of your room and that your personality is properly captured.
