Pretty good. The shading could be better. And the left eye (viewer's right) is a little crooked. But it really does look like Gren.

My freind always makes fun of him, but I just love his story!!^^ i wish him and Vicious would have gotten together at Titan. It would have added more intriuge to the story.

My friend is so obsessed with him it's not even funny. Good piccy, too!

I must say I prefer Faye but then again I would. Very cool Gren though, well done.
