In my experience, it can be almost impossible to say what will be judged well in a competition. I've seen 'winning' images that I would have tossed in the can if I had taken them. I also seen quite beautiful (to my eye) pictures that were passed over. Depends on a variety of factors including who's behind the competition, the theme, the focus of the competition, etc...
Anyway, good luck!
exactly, sometimes i dont understand how can some photo win.
like you said,sometimes i see on first places photos which i will leave in the darkness of my harddrive
