Yes they are eventho they are in a very low resolution. There are pro who can redraw them manually or appsoftware that can make them to a high res.
My side is different, a bit harder to edit because they re animated. mostly, I include my username not because Im protecting my work, because I m challenging them and part of my typo! Aside, those who liked my work, they simply request or ask permission to use by replacing the main render, change name and etc~ someone also want to pay in return but I decline, what are friends for if i receive payment? Oops this is your story, sorry to include my little story, again am just bored, power interuption occured again
