Very good likeness. Don't let the scanner get the better of you though. If you have Photo Paint or Photo Shop justs download it to there and do an auto adjust. Then edit and resubmit to dA.If you don't I would be willing to do it for you.
Whenever I look at your character designs, the word that comes to mind is "soft". They look so gentle and soft. It's a very cool style and extremely pleasing to the eye. Your characters have a way of connecting with the audience through the eyes and it's so captivating.
