Great detail and personality you've captured here. I think it could benefit from a VERY slightly wider crop and a bit more contrast though, maybe even some selective brightness/contrast boosting in the eyes to bring them out more. Good luck in the challenge :]
Nicely done - perhaps a little lightening around the eyes would help? The obvious thing would be a catch-light, but this has a feeling of a non-studio shot. Without some sense of light in the eyes a face tends to look somewhat lifeless - but in an image that strongly suggests a hopelessness (rather than survival, resilience etc.) that's maybe the more real approach. Doesn't mean in won't just take the edge off your score for many voters, though.
