I must agree with Jazza- the hair is fantastic, and is amongst the strongest points of the piece, along with the realism of the saliva and the clothing. You've also made a good attempt at a hiss/roar, as the subject changes from one form to another. It could use a few minor tweaks, but you've still done a very good job. Keep working at it!

Very nice! You've done fantastically well with the hair texture, you must be very very patient! The details in the mouth and eyes are good and the skin tone is excellent. I will mention that the facial proportions are a bit off, the eyes should be more centered in the head, but overall you've done really well, keep up the great work!
