I think despite your colorful hair and piercing and tattoos you have kinda "classic" look.... your face looks "normal" (in a good way... you could probably model some conservative clothes (can't piercings just be taken out for the shoot). You have nice symmetric features.

Sure you could totally pull the alternative look too. Depends what you wanna do with it. What would you be modelling as "alternative"? Clubs, music stores, clothes?

Maybe you could try being a hair model too, since you are not afraid to do stuff with your hair and you could get some crazy styling for free
