Work non-destructively

Now I hide my first sketch and finalise the new, more detailed drawing. To work non-destructively, I use as many layers as possible. I also paint the cat mask on separate layers and place them in a layer folder so that I can reposition the mask later if necessary. Non-destructive editing is a type of editing where the original content is preserved and not changed. This opens up the possibility of undoing any operation without losing data. Therefore, I would always advise to use many layers and also layer masks to take full advantage of digital working.
