Yes! Now this is what I like, the emotion is spot on, and I feel the pose really adds to the drama, super lighting really aids here.
Whilst the pose isn't exactly original, the posture and drop of your bottom lip adds a little punch. The off sepia toning with a little green added really gives this a great feel. I do however think this could be improved if the background was umongst something stereotypical of a nerd? Although the idea maybe a lil to cliche, sometimes this works.
Exposure is spot on, as is the lighting, and generally works really well.
Great stuff, really cant get much better apart from the background being a lil more interesting.
