Galactic space scenes are a popular theme for digital art, they’re packed full of texture and vibrant colour, which are two ingredients of an awesome design! Using Photoshop’s blending modes along with a mix of textures and brushes, let’s get lost in space and create an abstract cosmos poster design.
