🔶Checking mistakes. As you work on the same drawing, your eyes get used to seeing the image one way and you start missing mistakes. In case of a portrait, for example, you can easily paint one eye bigger than the other and miss it😳 Mirror reflection exposes all mistakes. As soon as you glance at your art in the mirror, the canvas will be “flipped”, and errors would jump out at you. Digital artists can flip the canvas in the app but if you paint in a traditional way, mirror is super helpful.
