When I’m creating abstract designs I usually work on three images at a time. The reason for this is to explore the possibilities of individual tools in Procreate app and to consider variations on a specific compositional theme. Therefore, all three of these abstractions have several things in common. They share subject matter composed of geometric shapes (circles, rectangles, etc) and various uses of lines. Their color schemes are related and all three evolved using the same few tools in combination.
All of the designs were created using multiple layers in Procreate app for iPad. The texturing of each surface was done separately in iColorama which is a photo editing app that works very well to alter the look of original artwork as well.
