There are 3 words to say that i'm quite satisfied with ACGC.

"Marina", "Soi Fong" & "Eclair"

(from Gundam 00, Bleach & Kiddy Grade)
Other than those 3 cosplayers, i don't recall much about ACGC since my minds was thinking more about the arcades or my sleepiness most of the time i was there.

Requesting pictars of those 3 cosplayers pls.

eclair damn flat maa. I need to photoshop her boobs

we still have a long way to go, compare to our japanese counterparts. 
The seriouness they put into the cosplay are by far bigger margin compare here. See the fake hair also can't cover the real hair popping out.
