Beautiful facial expression. I love the detail in her hair. The extra wisps of hair and it's composition adds to the flowing and free nature of your piece. Great choice in background colour. The icy blue adds to the feeling of freedom and it's nice to see the character in this light given some of her circumstances and possible outcomes in the game.
You draw her very beautifully. The colouring of her face particularly looks great. I wish I could do that, my style's still too... manga influenced though I'm trying to get rid of such habits, it doesn't suit me.
+ She looks like a prettier version of what my sister and I would look like combined.
