Luna - Selene Picture

A drawing for a project in school about the moon. This is the moon goddess Selene (greece mythology) or Luna (roman mythology). I feel so stressed, I have four tests this week @___@ Not that I need to worry about the English test, but the biology and this project freaks me out!

Now, how should I color it? Or is this good? @___@ *confused* MOOOM?
