I want to play a character from a visual novel, but the novel is very text heavy, has very few images of character art compared to modern visual novels and mostly reserves expressive art for the main character as a result of being a psychological horror VN. So although the character I want to play is important to the plot, I've only got four icons for her if I use official art.

Now, the normal work-around for this is to use fanart. The problem is that the fandom for this is pretty small, probably as a result of the game being twenty-one years old, and most art is of the main character and/or his love interests, so using fanart just brings the total up to eight, and they're not a wide range of expressions, either.

So I'm sort of stuck on what to do. I don't want to use crappy icons, a small number of them or worse, have both of those problems at the same time. Is it acceptable in DWRP to use a PB under these circumstances? Should I put a little disclaimer up on my character's profile to make it clear she's from a VN, I'm just using a PB due to lack of other options? Is there a way to find a manga character with similar features and use icons of them, or is going for a live-action PB a better idea?
