Great,Fantastic Possibly the best Star Wars Fan art I Have seen in a LONG Time Amazing use of Lines and Great look! Good Job ;D
For improvement I would Say Toning Down some of the Lines near the Top of the Head and the eyes Perfect detail,I;m going to have to say this PERFECT! Well Seems like I Have much room left,Time for more Complements! The use of lines really gave it a great feel of menacing Same goes for it being in black and white and the eyes and the mouth are just perfect Good luck on Other pieces of Art!
