Celebrity head Sketches

Decided to take a more cartoony approach to drawing with a heavy influence of anime.  I've been drawing people with an almost exact likeness to the reference and it was no fun.  Part of the fun thing about being an artist is playing around with proportions and discovering new styles.  So I've been painting my sketches with new chalk brushes and I like the way it's working out.  Although I still have a lot to learn, I'm catching on.  Can you guess who these characters are just by looking at them?  Here's a hint : One is from the WWE, one is from Iron Man, one is from GOT, one is from Arrow, and one is from Orange is the New Black.
