This person has a really nice expression. My only suggestion would be that, with teh way you've posed the shot, you need a bit more negative space. I think the expression may even be enhanced if it stood out against a bit more of a background/negative space. The jaw bone isn't as important in this pose as the smile and eyes so the composition just needs a tiny bit of a jiggle. Overall a nice portrait though. Good luck!
I'm not sure how you did this, but his face is too "porcelain-y" for my taste. That's just me, remember. It's kind of flat or something. The little blue spot on the upper right corner is a bit distracting. I can't vote so don't worry, I didn't bring down your score!
I like this funky white/fade look here. I will say it's not very natural looking..?beard? Still for a close shot as this one, it's okay. I think the crop is alittle close to his nose and I wish we could see his eye more. Not a bad shot. Hope ya do well.
a bit too close, and a bit too much of a side view. profiles work great if you can see the other cheek, but so that the nose doesn't "cut" the line of the cheek, so that you can see the other eye.
