You did some subtle things there... it was cool. I had to keep looking to see. I think I like that ring of white around this one. I assume I could change that later. And it took me a bit, but I noticed the eyes in one are focused forward, and another off to the side. Cool! (could you please just note the changes with new revisions)? I assume I'll like some with one thing, and something else about another.
1. The shadow is on the right side of the face. Let's remove.
2. Also, I noticed a little sideburn. Girls don't have those. :)
3. The hair I mentioned.
4. The glasses... here's a link to what I have now:

I also like the glasses done by another designer in picture 21. I'm not looking for you to copy. I'd imagine that's not cool. It's more an example of that kind of geeky glasses. They're like the classic Ray Ban:

I'm sorry. This all means I'm excited about it. I hope you're not offended.
Thanks!!!
