Aye, I'd expect something like that to change drastically heh. Man, I know absolutely nothing about JJBA styled sprites now that I think about it. They long and thin like that huh?
The only things that I'll mention are that right hand (artist's right) which I don't know if the pose is right for, and the fact that she looks very cyclopic but again that might be the pose and the style in general heh. Otherwise that's not bad at all as far as I can tell!
Actually, yeah kinda. There are examples of muscular characters as well, but in the end, JJBA has the most fucked up proportions, right after SF3 Here are a few example sprites from "Heritage For The Future":
Spoiler: Fuck ton of JoJo (click to see content)
Keep in mind that for Prishe, the changes would be drastic because it's literally a conversion from one art style to another (Nomura to Araki). As for the face, the examples above kinda look like that, save for some poses. I did try to keep it to Prishe, but like I said, you're the final contender.
What would you recommend for the hand? I'll jot it down on my list so I can post it with an updated Toph, and hopefully Palutena!
