it looks okay but not really great
The add-ins look pretty obvious and are a bit abnormal (to me anyway) and i assume that you don't want people thinking that as soon as they see it

As soon as looked at all the faces i noticed it in this order
1st: nunnally's mouth is wrong somehow unless it was deliberate because she's blind at the time and tried to put it on herself and messed up
2nd: C.C. lips are wierd(guess that was supposed to be the lipstick but it still looks weird)
3rd:Nina's hair looks spray painted on(maybe that's what you did but it looks amateurish)
4th:Shirley and C.C.'s eye lashes are way to thick(but thats just what i think)

I hope you don't feel bad about it because you really did a good job otherwise and i'm sure it wasn't easy(i should know i suck horribly)

Wow, this is one of the better group pics I've seen for Geass. Nice touch with all the add-ins, anime seems to lack eye lashes for some reason, and only the dedicated artists go for lip stick, lol. And C.C. smiling? That don't happen often. Nice work!

OMG, I'm melt as butter in the oven . . .
Very very pretty . . .
