I think miscdude meant the neck looked to thick, not too long. I sort of agree, and I did a small edit (hope you're cool with that, alk):

I did a bit of a general edit on the face, too. You had some banding going on in places (in places your AA... overlapped, for lack of a better term and caused blurriness), especially in the hair. The chin, too, I edited, as I thought it looked a bit small.
The pose, colouring, all that stuff looks pretty good so far. Looking forward to seeing it finished.

P.S.: looking at my edit now, I think your original hair is quite a bit better. The chin, neck, etc. changes should still be... somewhat valid, at least if not entirely useful.
