I would say when you draw a certain character make their facial structure and body shape look exactly like the characters we see in the anime or manga but make it 90% accurate and 10% would be your own per***al style you add into the characters. So when I see an artwork I would say oh wow this character is looking exactly like the character I see in an anime but I can recognize the artist because he added his per***al style into it which made it more lovable.
I hope everyone understand what I am saying I am not good with words

lol I said p-e-r-s-o-n-a-l

if you're referring to body proportions I prefer it to be as accurate as possible, including with young-looking characters. I see no rea*** no logic to go an pick up a character you like and inflate it as a bimbo or slut or whatever; for example: I would never ever draw Rukia with Inoue's size breast or a huge ass way bigger than what she has. I like Rukia the way she is, why should I change it now? I appreciate her with all and her more juvenile flat-chested body. I always find it extremely unfaithful to grab a character that is not anything like Matsumoto and to give her the exact same characteristic... after all, you're just making a clone of Matsumoto but smaller (maybe) and with black hair. I don't mind making tights, breasts, ass and other things slightly bigger, but to really exaggerated point? No, thank you. And this also applies for curvy girls; I don't want to draw them with less boobage and thinner thighs, let's them to be as curvy, maybe slightly bigger, slightly smaller than the original reference, but not completely reversing the character with a non explained rea***.

Now, if you're relating to the style... I prefer the style to be as accurate as possible too as I like to think it came from an episode or something. I know it's non-creative at all as you can't experiment that much if you're making what others do, but as said above, you can always add some of your per***al styles to make it is more recognizable than 500 artists doing the exact same. with things that have no canon material, like OCs or something, I always prefer to see the artist's style at full, so you can play with different styles for the same non-existing character.

I understand that physical traits are bound to get exaggerated on these sites, but changing a character's body type so it doesn't resemble the original makes a pic look off to me, like it's not even the same character besides the face. I might like some pics with this due to the pose, expressions, or background, but would enjoy those more with a figure similar to the characters drawn. In the end though, this is just a preference and everyone is free to enjoy something even if I don't.

I'm not as picky on the coloring style for points already said here.

If i want porn of a specific character it’s because i want her as it is. Say if i wanted someone bustier, I’d just ask for another waifu.
