Ok, Critique..

The shoulder..looks.."misplaced" it's too slanted down...
The neck it too long and skinny...

the cheek looks a little...bit..big..

the shoulder..bone thing... uh.. xD
...it doesn't make sense..you should at least be able to see part of the other side's other..shoulder..bone..thing..xD

Otherwise..i think it's good =]
