Yes, I know...but that distortions does not happens with, for example, Juri. And also, you can convert Urien to SF3 or even CvS without so much problem. But the same problem with Cammy happens with Chun Li, Ryu/Ken and some others. Maybe, as you said, the overexagerated stuff, but this seems to be noticeable in certain characters.
This is what I'm talking about:
EDIT 2: Here's one of SGV's inconsistencies:
This animation was directly ported to something similar to CvS size. I just traced in black outlines and a flat colour on it and then added details to it. No extra resize was done(I mean, certain parts or etc), so maybe things like these, bugs me.
The SF4 pose comes directly from resizing to a screen size similar to a CvS capture, while the SFV too...but the result is pretty different. SFV is bulkier. Not saying the result is bad(it's quite good, indeed), but lacks something that makes it fit in a CvS styled sprite...I don't know how to express it, but it's similar to Chun Li's SFZ to CvS port. They resized her for CvS1 but clashed too much with the rest of the cast(strangely, this did not happen with Killer Bee)
