Entering an Art Contest

OK, so I want to enter this contest. I even have a picture. The picture may or may not be done. What I mean by that is that I have no clue whether it's good enough. I thought it was winning material until I saw this one picture by someone roughly half my age who had madd skillz.

I realize there's only so much I can do right now as far as technique is concerned. I'd like a second opinion (and a third, and a fourth) as to what I could do better, but I don't know if I can actually make it better. At least not without scrapping a lot of my work.

Really, I don't know what I'm trying to say. I know I'm agonizing over this way too much. It's not like I'm super-invested with the contest. I know my chances of winning are slim. And even in the off chance that I win, what then? Do I lose the rights to my work? Will it end up in the hole that is DevantART, posted by 100 people that aren't me? Still, I want to enter, and I don't know why.
