Dev, user. If you're still lurking. I made an edit of your sprite. I would have gone something like this...

I know. But I didn't like the original design. I want a rule 23 design that at least retains some aspects of Mario. So a bit of chub and curly hair.
If it's any consolation, I did technically draw directly on top of his sprite, and move things around, until it looked the way you see it now.

The one on the right is good

It's still fundamentally an entirely different design though; it's your own personal take of the concept, not the devs original intention. From what I can tell, the dev is trying to go for something more Eastern/anime style, while yours is more Western/cartoon style.

I said I KNOW. I just didn't like his design. Too thin. Lacked titties. Hair too straight. What's the point of rule 63, if it doesn't retain any aspects of the original character? Then it's just "anime girl in cosplay". IDK, maybe he'll like my design better too?

This is unironically soulless vs. soul. The original sprite is just Mario but generic anime girl, the one on the right actually looks like she'd be wiggling her fat ass down below your sink fixing your pipes. I can even imagine her accent. Good job user, genuinely

Completely incorrect. Study for a few more years before you start giving your dev opinions.

Some people are just weebs and want their shit to be weeb-oriented

NINTENDO

True. But maybe he isn't a weeb. Maybe he would like something like this.
Also, there are chubby anime characters. If this is too western, I could make the eyes bigger and more uguu~

Wow, that's really good OP!
