This looks nice, although you need to work on the lighting more - if the source of light is behind the subjects (in this case the moon being behind the girl and the temple), then they're supposed to be darker and more shadowed with only their edges illuminated by the moonlight (like in this case for example: link).
Also, while the vector is pretty good and neat I see you used paths. Paths are more convenient and take less time but they also lack dynamics and crispness that shape layers offer so I'd suggest to use shape layers for better vectoring results.
Keep it up!
