Bombergirl [PLAYABLE CHARACTER]

[Baegal]

honestly I think the head you have now is fine.
I mean, we are going JOJO style, but one of Bombergirl (and even Bomberman)'s defining traits is the large head. It also helps show that she's meant to be a younger, smaller character. I mean, of the portraits we have now, Chris has a human-proportioned head, but it helps with the large character physique.
Nick has a caricatured head size, which works perfectly fine IMO. I don't know if mine is the best example, but Ocks also has a slightly larger head.
I mean, Gors even still keeps the same proportions as Gilbert normally, which looks fine to me.
