I don't have a drawing of it (nor have I actually started the story of their relationship) but I have a romance between two chubby boys, one an interspecies hybrid, which is, for the most part, a metaphor for being biracial, and the other an emo-of-color (I don't know his ethnicity though. It's not confirmed in the canon media)
