I’m always playing with brushes, shapes, and designs. I will often start by just randomly scribbling some values and tones down in Photoshop. Then I will use the warp tool to change it. Warping a shape multiple times will sometimes give me incredibly realistic detail while other times it just makes it blurry. Thats when I go back in and paint or draw in the details by hand if the shape is interesting enough to me. I then sometimes mirror the shapes or combine different shapes to create new shapes.
