The contest was about showing us an old piece you had finished, and drawing the same image again to show us how your skills have improved over time. Showing us the rought draft of your work from 4 years ago and then showing us the finished piece doesn't seem to fit in with the subject of the contest I think.
I'm stuck somewhere in the middle, lol, you made great progress since then indeed. and I get what u mean, it's all about daring to use dark pencil parts where you think they shouldn't be used. having a white skin colour doesnt' mean it can't look black (or vice versa) lighting lighting lighting, that and proportion, obviously, just overall, can only say I like your work, hope u make the best of it
