Okay so this is gonna be really embarrassing but I literally just found out about this today??? Man, I gotta check my emails more often...
I'll probably make some when I unbusy myself from the webtoon contest and essentially rewriting a good chunk of my comic's first season. This is a really cool feature because now I don't have to look at the comics on the front page and be like "man, I wish I could a cover like this on MY comic..."
For some reason this brings me back to the good old days of playing around with Picmonkey (since I used to use picmonkey before everything essentially became paid features).
