Here is some more artwork based on the digital marbling app Edru. As I worked, some of the images stared to look like critters. Here are a couple of examples.
These two paintings started with the same image I created in the Edru app, with different backgrounds applied in Procreate.
These two are layered with backgrounds created using iColorama, Metabrush, Procreate, and Waterlogue apps.
Finally, I belong to a Facebook group called iPad Artists – All Included. One of my pieces is included in this video of artwork from group members.
