Self-portraits are fun, aren't they? Well, they CAN be fun anyway. The main issue with this shot is not your pose or you but the color cast. It is very red/yellow overall and that keeps your wonderful hair from standing out. It becomes one more red thing in a host of other red things.
I think you should have done better as well.. This isn't a ribbon shot, but, it's much better than a 4.75 overall.
In any case, I think a much sharper eye would have helped set this off.. You have beautiful eyes, accent that and work with your obvious strengths... I would guess a selective sharpening of the eyes here and a small sat boost to the eyes would have made close to a 1 point difference.. That, and if you would have kept that thing out from in front of your face... Stop hiding and show us your wonderful face!
I really think the score was unfairly low here. I gave you a 6--in its technical respects, this is respectably executed, and the crop lends interest to the composition. DPC voters are nutty sometimes...
