Renault Twingo my beloved

Little context on the characters (Stolen inspired from Love and Hex):

• The right one is ST Louis from azur lane. Yes she looks like that. Yes she has back problems. Next question
• The left one is Olist, one of my characters. She's a street racer and car freak.

I've never understood the appeal of characters with breasts that large. What's the threshold where it switches from sexy to grotesque for other people? They're literally bigger than her head!

Same. I only used her because of her association with luxury cars as another layer to the joke and because some of my friends like her

I had a quick search. I enery other depiction, the character had a really big tits, sure. But they always were somewhat well drawn or modelled, so they don’t look that out of place in context.
Op version us just tasteless slop. Nothing more.
So to answer your question, op’s version is revolting while original design seems to usually have very large yet still appealing ones.

Above B cup is too much. Fight me.

(Please don't)

I'd like to point out the official art. They are like that.

You missed my point. There is a difference between big and nice and big and not nice.

TBF the comic isn't about them either. I just took this character as it was the most relevant to the joke, and that some friends like her. Never wanted for it to devolve into boob related drama.

And I only post here because I made something. I didn't make something to post it here. So if people like it then it's good for them. If they don't too bad

IMO this is over the line. Not grotesque per se but just, comical. It's not appealing.

Go on, I'll fight for big boob girls. Big boobs are great (but also so are small boobs).

Well.. they applied gravity. You... kinda did not

I'll defend the honor of small boobs.
