It has been noted that now that Soul Eater has officially ended less submissions come our way. Nevertheless, the criteria to get your art (or cosplay or fanfiction) accepted to the group's gallery hasn't changed.
The rules state that the group has been dedicated to the pairing Asura/Maka. Therefore, it should also be stated in the rules that only artwork that involves these two in some way, is accepted. I do not know why it hasn't been included in the green rulebook since I'm very certain this same problem arose during the starting times of this group.
It makes me sad to have to decline your artwork just because it only contains one of the involved characters. We understand that you want to promote your art, but there are plenty of clubs and groups for individual characters of Soul Eater. It is another story entirely if you cannot find the said clubs so just in case, I'm putting a few up here:
