I like the character, especially the expression. Suave and yet geeky...I like it. Plus I'm a Star Wars fan.
But the lightsaber effect! There's room for improvement, I'm afraid..Is that an A:M effect or was the lightsaber edited in Photoshop or a similar program? If it's Photoshop, I know how to make the PERFECT lightsaber. Of course, most people will just look at what you have and say, "Hey, great-looking lightsaber!" I just happen to be obsessive.
Anyway, excellent job! And sorry for the pickiness. I'm looking forward to seeing the final clip.
