The light is good on the photo, I like that! I guess you've sharpen the eyes and mouth? I think it's a little TOO sharp now! Ans maybe you can let them both look away ór both look at the camera. But that's my opinion. Hope you can do something with it!
It looks a little over post processed to me. Their features have a fake look to them.. too much makeup + too much sharpening. Also, not enough natural light. I like the pose though, its cute.
