I googled a fanpage of Cammy pics that I'm looking at now to compare to this, and it looks pretty good from what I see.
The right side braid looks a little thicker to me, not the left (your right if you were wearing it), or the left side is braided tighter/denser depending on how you want to describe it, BUT I think that's partially the lighting / camera angle, and it's a barely noticable difference anyway.
The hair in the front is a little too thick, as Kat said and in the pics I'm looking at it's... well here, this Pic is by one of the SNK artists, and they do their drawings a little more realistic then the Capcom guys so maybe it'll help show what I mean in regards to how it'd look on a real life costume...
So I think if you thinned it abit that might help a little.
Although Cammy has been drawn 'officially' by something like 5 artists, and unofficially by about 5000 more, so I could just be going off differant versions then you're looking at.
Anyway, really that's just some helpful nitpicking. I think if you put it on as it is it'd already look great, so at this point you'd just be refining tiny details most people probably wouldn't even notice unless they had a picture of the character in hand.
Best of luck in finishing it up!

"Yeah I know... all I got is several non-CP shots in my gallery... not all of us first timers can Macguyver together a costume from two pieces of dental floss, a stick of chewing gum, and an apple core like Mandy can."
