Dude, I have not answered your PMs yet!
You're fast!
I really like the start of it. Im not really sure how it should look in profile but you got something going there so I might just leave it up to your creative juices to flow.
But I can always draw something to choose between if you'd like some ideas.
And about the brow, he looks a bit more angry with the two-part then the unibrow, so to speak. So I guess its up to what one want the bio to "present" I guess. Maybe people can chime in on this and say what they like the most? I myself think the two-part looks better, but can be changed to kind of like the Mr. Black bio brow.
And of course, THANK YOU for doing this! Its always great to see drawings come to life like this. There is alot of great bios out here, just amazing what people come up with.
