First of all, a deletion PM has been send to you along with some additional information by the moderator who deleted it.
For deletion appeals, it is highly suggested you copy/paste the PM in the first post.
Seems your work was deleted because it was of Doujinshi Quality. Another mod can bring you more information on this
matter. I'm not sure about quality control in the Indy-art section as it is not what I manage, but I can tell you
that you lack a description and I can't really tell anything by the signature. This does mean that you lack the
proper qualification for legitmacy. For that reason alone, your work will be deleted.
Some things we look at and are a requirement:
-Signature/name in artwork that we can recognize (just write your username there aswell)
-description in your submission about your progresses, ideas, sources(most important), techniques, anything related to
your submission.
