I think it's important to look back at your old art. While it may make you cringe (did I really used to draw like that, #yikes), there is something endearing about the exercise, and sometimes a little perspective can be the best confidence boost.
Here we have an example of a young artist obsessed with the hot-new-90s fad: Pokemon, vs a newer piece drawn 20+ years later.
(Though who am I kidding, I'm still in love with the franchise, including this iconic mascot, haha)
Seeing this artifact is especially important as the reason why it was preserved for so long is thanks to my father who has kept this doodle--and many others--tucked away in his personal affects.
There's a lot of perspective to gain on your own work, when you realize that it can have an impact on other people, right?
