The palette is so different from what you usually do and it's a good thing. The night scene is somber and mysterious. The alien girl is full of energy and still graceful. There is a story going on here. Is she racing to the space port so she can steal a ship and fallow the rocket we see escaping into the sky? Who or what is on the rocket that's so important she has to exert so much energy?
The over all composition is good and thoughtful.
I like seeing you use the entire figure in your work.
Me? On a personal level, this has to be one of my favorites. It really tells a story without hitting you over the head. Good Work
