I use my phone to do digital art.Although the phone screen is small for digital art, it might have been more convenient for me to use a tablet.At first, I couldn't do very good digital arts either.But now that I'm doing it, the art isn't that bad.But I still feel like I have a lot to learn and my art isn't that good.I hope your son learns digital art soon too.Because I realized that it's relatively easy but requires patience to do it. Thanks for your valuable comment.🤗
