your KG is already looking mint as it is, but I'm sure it could do with some more tweak in the headshape.
Try comparing your ebo with a real KG pic (I know you've already done that but I'd like to see you do better) and concentrate on each part of the ebo seperately. The bheds are nailed from my view, but the ebo is what create realism

Not to bring you down though because you've done such a great job and you've just been through a network disaster which lost all your images. I'm sure that gave you a pretty hard time. Nevertheless, you're also busy with school works.. what I'm trying to say is dont rush yourself. Take your time and go through this slump step by step. Soon you'll be out of the hole
And more power + support for you.. go Grant Hill!!
P.S. If you happen to have some spare time left from your already-busy-life, please drop by my thread and posts some comments
I'm dying for them!
