First things first...color, needs color!! :P
Other than that it's not bad, a little LQ but not bad.
You did show me the colored version already. From what I remember about it the depth looked a little off (it doesn't look too bad here) the colors were kind of random and the face was way too prominent. And the border was very strange from what I remember, if there was a border.
I know how it feels to start up again, its hard. Styles have really changed since me or you have been around and it's hard to get up to that new level of decency.
All in all though it's really not bad just keep color in mind. Black and white is just too easy haha. If you can get the color down on top of a decent picture then you're gonna have a great piece! Keep it up man. Lemme know when you finish that other sig you were working on!
