There is a website that looks at all your Instagram posts for the year and generates a chart of the most-used colours. Here is my chart for 2018.
Here are a few recent abstract paintings.
I used a new (to me) app called Isometric to create the geometric shapes in this painting, then layered it with some of my metallic textures.
This painting was created in Flowpaper, Artista Haiku, Procreate (blended with one of my alcohol ink textures), and Frame Builder.
This painting was made using a background I created in iColorama and Procreate, layering with some scans of alcohol ink splashes.
And this one was created from scratch in iColorama, with only the framing done in Procreate.
