Tobi - Naruto

Hey guys. I decided to draw Tobi because I was watching an episode of naruto, and he looked so cool to me, so I decided to draw him in a kind of sketchy style, but using Micron Pigma inking pens to give his mask a sketchy manga look. I added a little twist of shading.. get it? His mask? Like, a twisty design..and like, a twi- oh never mind. Please tell me what you think, It's pretty much my first time actually colouring in, and I think the result is okay.
Thanks
