Very neat
~~REVIEW~~
Wow very nice, a very good sketch of vader maybe give im a more broader presance more dominating from the smoke, also i like the smoke like feel from the backround, but maybe some "EYES" in the distant of the backround, also having the sabre lit up would have been good too, just a few ideas to show more of Darth vaders Domination and evil that he brought to the films, So anyways i suggested some ideas, but the rest was great and a great idea you have here, anyways nice idea, hope to see more from you soon.
~~THINGS TO IMPROVE ON~~
Well as suggested more prop stuff like the lit up sabre, and some more darkness like eyes in the backround and such.
