Are these good body proportions?

Uh... No. Even if on purpose the waist is really off-putting. Too sharp and too thin. Women have softer, less dramatic curves. 상단, 맨 위로 half of the torso is also a little long. The boobs are also a bit big although some women are that size.

And I would say no to your bonus q. I feel like it's not the same kind of 애니메이션 and breasts like that aren't really in kid's cartoons.

I think it's fine. I see proportions like this in my comic books. It's good! :D

I honestly don't think so. the waistline is too intense. even for a cartoon. and the boobs? they are rather large. Also the bottom half compared to the 상단, 맨 위로 half seems rather off, as well as the forehead is too small, lips to large, and the eyes are too close together.

And to answer your 초 question, holy fuck i hope not, i honestly don't mean this the be offensive, but i find her to be a little bit to skimpy to be in a kids cartoon.

i don't mean to offend 당신 but... NO WAY

She seems too thin to me. But I suck with proportion so...
