self portrait for crit

i had to tak a self portrait for a magazine im contributing to (its even written on my hand...), so i thought i'd have a bit of a muck around with lighting etc.
this is the shot i liked the most, i'd like some opinions... it's the first time i've had a crack at this sort of thing, so dont be too harsh... but don't go easy either!!!
taken with my d70s wearing a 50mm 1.8
the camera is sharper than me, on purpose, i wanted it to be more about the fact im a photo guy... the camera is my tool...
