Tainted Angel(Color Practice)

"Let there be darkness within you.."
(That didn't fit well...oAo")

I always keep changing my coloring, it's quite hard you know to know which is actually perfect. I like the hair but needs a bit of fixing. I'm searching for tutorials. I use mouse to color my drawings all the time and tablet for sketching.
Oh.. forgetful me, I forgot the lines, some curly in my hair.-_-"

My hair is now a bit long today. But the straightness of my hair is faded...-.-(I need to go to the salon to straighten up my hair)

Used Paint Tool SAI and Photoshop Cs5.
