What is a good cosmetic brand for a Teenage girl?

MAC? Stila? Shu Uemura? Bobbi Brown? Hard Candy? Sephora?

I’m currently hooked on MAC, I love the artistic style they put into their ads, and products..but lately i’ve been thinking, what if it makes me look ‘too painted’ I need to try out other brands .. any advice? any good makeup tips or brands for someone my age?
To be more specific
I’m 14. almost 15. I’ve got oily skin. I’m really into the whole ‘rocker/grunge/punk’ look as i’m greatly influenced by the music of it.

Budget: well nothing too expensive (sometimes only for special occassions) and nothing deadly cheap of poor quality
