I'm having the same problem as Rambo; the more I look at mine, the more I despise it. Mind, its just a sketch at this point. But not drawing for weeks at a time, and not really having the drive to go through the effort of doing so, makes it frustrating.
I got a friend hounding me about it, though, saying it'd be blasphemy to NOT draw something Metroid. Thats incentive enough, I suppose.
