Digital Art is art that is digitally made. Son of 8 years old also made his own art a long time ago, on the Iphone of my husband. Nowadays you can of course much and much more with all kinds of apps and programs, but then it was actually just introduced a little, to be able to draw or color on the phone, I think. Unfortunately I don't know what program he made this with, but the pictures have been preserved all those years.
So keep in mind, that it was quite a few years ago, and made by a child.:) Personally a nice Art reminder, for another maybe some colors in a rectangle.
