I recently requested a cover/poster from this shop for my fanfic "God Knows I Tried". The designer, omona-mark, didn't really have much to work with since I was clueless about what I wanted the cover to look like. However, the results were nothing but satisfying. Definitely check this graphic shop out. Here's the link:
