Who should I cosplay as?

Ok so I'm deciding to cosplay for the first time and want a fairly simple one.
I'm not going to a convention.
I'm actually doing this for Halloween xD
My mum doesn't mind me doing Gothic Lolita or anything Loli but I don't
want anything TOO revealing, if you know what I mean.
First things first, I don't want to wear a wig.
I have black hair if that helps.
I'm Chinese.
I'm 5ft 4/5''. I'm actually not sure xD I'm pretty tall though.
Colours I like are black, red, purple and green.
I don't want to go as a Pink Loli as I don't like Pink.
I love rock, punk or gothic styles.
So any ideas? Plus include some ref pics if possible?
Like from eBay or something? xD

I was planning to cosplay as:
Rukia ~ Bleach (Both Soul Reaper or School)
Teru Mikami ~ Death Note
Hinata ~ Naruto (Without the head band or contacts)

Cosplay Items I own:
2 Death Notes
Naruto Head bands, Sound, Mist, and Rock Lee's.

Maybe any Akatsuki Members?
