Will this be a JRPG or Western style?
By which I mean will the player be building their own character and picking out every trait and appearance (western style) and then possibly attract companions, or be a predefined character out of several with all their abilities and appearance chosen by the game designer (JRPG)?
This makes a significant difference. In western style RPGs there's a conscious assumption that to some degree, the player is building a self-insert (and goes so far as to make the character a person from out world inserted into in the Ultima series) so a first-person perspective could work. On the other hand if the "main" is very unique and stylized and a character in their own right rather than a player-insert, making it first person wouldn't be as good, particularly since their exotic appearance is probably a major draw.
