I have problems with that pic (C.America), but at least from what I know of that artist, he was consistent with that kind of work and you could write it off as 'style' (it's still wrong but at least it's 'stylized' to a degree, and most of the characters are consistent)
Kojima's (LOL you said Komija, teehee... **ahem** sorry) proportions vary by the day, it seems. Sometimes stuff is 'ok', other times it comes off as wildly out of proportion, by a large margin, even when it's the same character, only at a different shot/angle. I love the way she draws faces, but when having to do a full-body shot for illustrations, seems she doesn't believe in touching up her works in post-production. It's like **scribble** **scribble** **shade** **shade** **color** **color** "OK it's done" and nobody tells her "That's nice but the proportions are done. Please do it again or hand it to our post-production team, who will inflate the head, shrink the body vertically, and align everything correction, then return it to you to finish up".
Picasso was doing stuff just for the sake of art... she's not. She's doing a character illustration, like a commercial artist would, only it's a person (as opposed to a can of soup or a box of cereal). Style is up to Konami, so either they don't care that it's offfffffffff, or they cannot afford/don't have the gall to tell her to fix it.
