You're welcome. Thanks for yours as well and your interest.

I'm a little uncertain about your question?
Artwork is not compulsory, you could just enter text. It's really up to you how much you want to enter, the limit is your imagination in regards to the subject.

I hope that answers your question, if not please feel free to try to ask me again and maybe ask in another way using different words cause I'm not totally sure I understood the question.
Cheers! :)
