I'm not that great of an artist, so I'm not sure how well I can critique, so if I say something you don't agree with, just take it with a grain of salt ^^;;
I think overall the proportions and anatomy were really well done! There were some parts that I want to nitpick at, just the wrists. The wrist of the hand holding the candle was really tiny in my opinion. I'd widen it just a tad. I also thought the arm was a bit long...
The left arm (her left) if I had to get really nitpicky, I'd say that it's hard to distinguish the lowerarm from the upperarm? I'd add some curves to differentiate between them.
The legs I thought could be lengthened a little too, but I'm not sure if that's because of my style. I always draw the length of the legs = the length of the overall torso.
Er... if what I pointed out were just part of your style, then just ignore what I said.
Coloringwise, I really like the way you colored it. It reminds me of watercolors ^^ I guess if I had to critique it, I'd say you could push your values a little more and make her look more "solid" Just deepen your shadows (darker shadows emphasize how bright the candle is, I didn't do that good of a job because I'm not good at coloring myself. >< ) But yeah, more values can definitely add to a picture.
