He does look great. I think if you maybe lowered his brow a little more and maybe narrowed his eyes a little bit more, you'd get the more ominous looking Anakin that you wanted. Otherwise, you did a very original style drawing and you should be very proud of how it turned out. Great work, hun.
Okay. The best way to improve is through trial and error. I will look forward to seeing a new one in the future. But don't sweat it. You are a great artist. ^_^
Thanks again!
