Not bad. Perhaps I miss the ehhmmm..."lines between the corners of the mouth and nose" (sorry, my english sucks, hopefully you get what I mean), right now it's a bit too solid there. If you add that, then just subtle, like in the source image. Ow, and maybe her lower lip is a bit too cartoony. Good luck!

Good source pic! The lower lip is maybe a bit too stretched, perhaps you'd like to make it more as in the original. Check the tear in this image http://www.flickr.com/photos/lisa_at_home/2746833785/ It's more transparent with a bit of shadow and a more stronger highlight. This way the drop gets more volume. Maybe you can make a same certain thing for your tears. Good luck!

tears aren't white. and the mouth should be closer to the nose

Please post source link...
