Well, I'm not sure how one even gets a verified artist tag, nor am I sure if I would even qualify as one, but I have created a couple of things.
Here, I only created the big in-focus text while attempting to blur out the background screenshot.
In this image, I only created, or rather re-created, the text, text boxes and general elements. I, however, did not have a hand in the creation of any other vector art nor icons. I believe I provided sufficient links to the elements on-site. Except the art brush due to an inability to locate a link to the original.
Oh, this may qualify me as creating something for ponybooru exclusivily.
