The way your hair looks in that pic you can do Jin kazama, Darrien, Sebastian and Ceil saving yourself from buying the wig!
You can cosplay whoever you want. These are just based on how easy it will be for you.
However if you want a challenge: Goku, Trunks, Naruto, Sailor Mercury, Gintoki Sakata, Cell, Blaziken, Gym Leader Juan. Have Fun <3!
