I love the bright colors and intricate details in the watercolor prints from SilverRidgeStudio on Etsy. Focusing mostly on fashion illustrations SilverRidgeStudio makes reasonably priced (usually $35-$200) prints that will liven up any room. I especially love the Vogue cover watercolors, which would be great to collect a few and make a wall collage!
