I'm sorry to be harsh but... that's... not how a body works ; u ; Crit time, sorry about this!
I see what you're trying to do but you're forsaking anatomy to do it. Your colouring and individual form for each body part is really great but you're kinda... focusing too much on the sexualization of each character and it's breaking their anatomy... or in this case, breaking Noel's spine.
I think you're trying to exaggerate anatomy, which is pretty common place but you're going about it slightly wrong and just breaking anatomy rather than exaggerating the rules of it. Like, for example, an artist who can really, really exaggerate anatomy but not break the rules of it, is Slugbox (warning, Slugbox art is VERY NSFW, but I'm posting some of his SFW examples):
Using foreshortening, perspective, and some exaggeration can create a really dynamic looking, "sexy" picture without breaking anatomy, and I think that's what you're trying to do but... yeah ; o ;
I'd recommend studying anatomy in general more, looking at the limits of the body etc and not trying to focus on a womans sexual aspect in every picture.
Your pictures are by no means bad when it comes to form, composition and colouring, just your anatomy REALLY lets them down and makes them look uneven. My earlier quote wasn't about the lack of BlazBlue, but the anatomy...
I'mma agree with Luca. You've got some nice colouring and colour coordination |D (just a bit eeeh on subject matter)
The subject matter not meaning the characters but forsaking anatomy for "sexy" looking pictures. I love Poison and most of the characters you drew, just... yeah.
Sorry to bring this up. ;; just thought I should say...
