To answer your question, I like the self portrait as it is except for my sweaty appearance from work
I used a bare flash on either side of me while sitting in front of my TV with minimal PP - I think only a little USM if I recall right. For the mood it coveys it's good. I like the hard light and the separation from background is good, though the crop may be a little low on my forehead. For a more friendly mood, I might try to smile next time and choose a more colorful background
What do you think?
