When you’re working on an iPad you have to think about layers in advance, because the canvas size and number of layers depend on the type of iPad and its processing power. For example, on my iPad the Procreate app enables me to have seven layers if I’m working at A4 size format. If I want to merge a couple of layers into one, I do it by tapping on them with two fingers.
Juggle those shapes!
Stepping back to look at the overall picture, it looks like the objects, light and shadows are arranged like a puzzle of geometric shapes. Like an orchestra conductor, our job is to manage all of it so that there’s neither too much nor too little of an element. The best example is a rainforest, where everything has its own place. It’s nature’s way!
